feat(security): implement template-based credential management for sensitive configurations

Introduce template-based approach to prevent credential exposure in version control. This security enhancement establishes a standard pattern for managing sensitive data across the homelab repository. Changes: - Create services/homepage/services.yaml.template with env var placeholders * Replace 7 hardcoded credentials with ${VARIABLE_NAME} format * Add OPNSense, Proxmox, Plex, Radarr, Sonarr, Deluge placeholders - Create scripts/fix_n8n_db_c_locale.sh.template with env var validation * Remove hardcoded PostgreSQL password * Add N8N_DB_PASSWORD environment variable requirement * Include security reminder to shred script after use - Update .gitignore with explicit exclusions for sensitive files * Add services/homepage/services.yaml exclusion * Add scripts/fix_n8n_db_c_locale.sh exclusion - Create services/homepage/README.md with comprehensive setup guide * Document environment variable usage (recommended method) * Provide API key acquisition instructions for all services * Include troubleshooting and security best practices - Update scripts/README.md with template pattern documentation * Add fix_n8n_db_c_locale.sh template usage instructions * Create "Template-Based Script Pattern" section * Enhance security guidelines with shred usage Template Pattern Benefits: - Repository remains credential-free - Templates serve as documentation - Easy to recreate configs on new systems - Supports CI/CD pipelines with secret injection Security Validation: - No API keys in staged files (verified) - No passwords in staged files (verified) - .gitignore properly excludes sensitive files - Templates contain clear usage instructions Related: n8n troubleshooting (CLAUDE_STATUS.md), Docker Compose migration 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>

+# Homepage Service Configuration
+
+This directory contains the configuration for the [Homepage](https://gethomepage.dev/) dashboard service - a modern, fully static, fast, secure fully self-hosted application dashboard with integrations for over 100 services.
+
+## Security Notice
+
+⚠️ **IMPORTANT**: The `services.yaml` file contains sensitive API keys, tokens, and passwords. It is **excluded from git** via `.gitignore` to prevent credential exposure.
+
+## Setup Instructions
+
+### Option 1: Using Environment Variables (Recommended)
+
+This is the most secure method as it keeps credentials separate from configuration files.
+
+1. **Create a `.env` file** in this directory:
+   ```bash
+   cd /home/jramos/homelab/services/homepage
+   cp .env.example .env  # If example exists, or create manually
+   ```
+
+2. **Add your credentials** to the `.env` file:
+   ```bash
+   # OPNSense
+   OPNSENSE_API_USERNAME=your_opnsense_api_username
+   OPNSENSE_API_PASSWORD=your_opnsense_api_password
+
+   # Proxmox
+   PROXMOX_HOMERAMOSLAB_API_TOKEN=your_proxmox_token_1
+   PROXMOX_PVE_API_TOKEN=your_proxmox_token_2
+
+   # Media Services
+   PLEX_API_KEY=your_plex_api_key
+   RADARR_API_KEY=your_radarr_api_key
+   SONARR_API_KEY=your_sonarr_api_key
+   DELUGE_WEBUI_PASSWORD=your_deluge_password
+   ```
+
+3. **Create the actual configuration** from the template:
+   ```bash
+   # Using envsubst (if available)
+   envsubst < services.yaml.template > services.yaml
+
+   # OR manually copy and edit
+   cp services.yaml.template services.yaml
+   nano services.yaml  # Replace ${VARIABLE_NAME} with actual values
+   ```
+
+4. **Set proper permissions**:
+   ```bash
+   chmod 600 services.yaml  # Owner read/write only
+   chmod 600 .env           # Owner read/write only
+   ```
+
+### Option 2: Manual Configuration
+
+If you prefer to manage credentials directly in the file:
+
+1. **Copy the template**:
+   ```bash
+   cp services.yaml.template services.yaml
+   ```
+
+2. **Edit the file** and replace all `${VARIABLE_NAME}` placeholders with actual values:
+   ```bash
+   nano services.yaml
+   ```
+
+3. **Set proper permissions**:
+   ```bash
+   chmod 600 services.yaml  # Owner read/write only
+   ```
+
+## Configuration Files
+
+### Tracked in Git (Templates & Non-Sensitive)
+
+- `services.yaml.template` - Template with environment variable placeholders
+- `bookmarks.yaml` - Browser bookmark links (no sensitive data)
+- `docker.yaml` - Docker integration configuration
+- `settings.yaml` - General settings (may contain some preferences)
+- `widgets.yaml` - Dashboard widgets configuration
+- `kubernetes.yaml` - Kubernetes integration (if used)
+- `custom.css` - Custom styling
+- `custom.js` - Custom JavaScript
+
+### Excluded from Git (Sensitive)
+
+- `services.yaml` - **Contains API keys and passwords** (excluded via .gitignore)
+- `.env` - **Contains environment variables with credentials** (excluded via .gitignore)
+
+## Obtaining API Keys and Tokens
+
+### OPNSense API Credentials
+
+1. Log into OPNSense web UI (https://192.168.50.1/)
+2. Navigate to System → Access → Users
+3. Select your user or create a dedicated API user
+4. Scroll to "API keys" section
+5. Click "+" to generate a new API key
+6. Copy the Key (username) and Secret (password)
+
+### Proxmox API Tokens
+
+1. Log into Proxmox web UI (https://192.168.50.230:8006 or :240)
+2. Navigate to Datacenter → Permissions → API Tokens
+3. Click "Add" to create a new token
+4. User: `api@pam`, Token ID: `homepage`
+5. Uncheck "Privilege Separation" for full access
+6. Copy the generated token (format: `PVEAPIToken=api@pam!homepage=uuid-format-token`)
+7. Use only the UUID portion in the configuration
+
+### Plex API Key
+
+1. While playing any media in Plex Web App
+2. Click the settings icon → "Get Info" → "View XML"
+3. In the URL, look for `X-Plex-Token=` parameter
+4. Copy the token value after the equals sign
+
+### Radarr/Sonarr API Keys
+
+1. Log into Radarr/Sonarr web UI
+2. Navigate to Settings → General
+3. Scroll to "Security" section
+4. Copy the API Key
+
+### Deluge Web UI Password
+
+This is the password you set when first accessing the Deluge Web UI at http://192.168.50.231:8112
+
+Default is often `deluge` but should be changed for security.
+
+## Docker Compose Integration
+
+If running Homepage in Docker, mount this directory as a volume:
+
+```yaml
+services:
+  homepage:
+    image: ghcr.io/gethomepage/homepage:latest
+    container_name: homepage
+    ports:
+      - 3000:3000
+    volumes:
+      - /home/jramos/homelab/services/homepage:/app/config
+      - /var/run/docker.sock:/var/run/docker.sock:ro  # For Docker widget
+    environment:
+      - PUID=1000
+      - PGID=1000
+    restart: unless-stopped
+```
+
+## Troubleshooting
+
+### Service Widgets Not Loading
+
+1. **Check API credentials**: Ensure all API keys/tokens are correct
+2. **Verify network connectivity**: Can Homepage reach the service URLs?
+3. **Review permissions**: API tokens need appropriate permissions
+4. **Check service status**: Is the target service actually running?
+5. **Enable debug logging**: Add `LOG_LEVEL=debug` to docker-compose environment
+
+### Configuration Syntax Errors
+
+1. **Validate YAML**: Use a YAML validator (yamllint, online validators)
+2. **Check indentation**: YAML is sensitive to spaces (use 2-space indentation)
+3. **Review logs**: `docker logs homepage` or check homepage logs
+
+### Permission Denied Errors
+
+```bash
+# Fix file permissions
+chmod 600 services.yaml
+chown $(whoami):$(whoami) services.yaml
+```
+
+## Security Best Practices
+
+1. **Never commit `services.yaml`** - It's already in .gitignore, keep it that way
+2. **Use dedicated API users** - Don't use admin accounts for integrations
+3. **Rotate credentials regularly** - Change API keys/tokens periodically
+4. **Limit token permissions** - Grant only necessary permissions to API tokens
+5. **Use HTTPS** - Access Homepage only over HTTPS in production
+6. **Restrict access** - Use firewall rules or reverse proxy authentication
+7. **Back up securely** - If backing up configs, encrypt the backup
+
+## Updating Configuration
+
+After making changes to `services.yaml`:
+
+1. **Docker deployment**: Restart the container
+   ```bash
+   docker restart homepage
+   # OR
+   docker-compose restart
+   ```
+
+2. **Standalone deployment**: Restart the Homepage service
+   ```bash
+   systemctl restart homepage
+   ```
+
+3. **Verify changes**: Check the Homepage UI to ensure widgets load correctly
+
+## Template Maintenance
+
+When adding new services or widgets:
+
+1. **Update the template** (`services.yaml.template`) with placeholders
+2. **Document the new environment variables** in this README
+3. **Update your local `services.yaml`** with actual values
+4. **Commit the template** to git (not the actual config)
