Add multi-item Jira ticket creation from Ivanti Queue

Select multiple queue items and create a single consolidated Jira ticket
with aggregated summary and description. Adds multi-select mode with
checkboxes, floating action bar, consolidation modal, and junction table
to track which queue items contributed to each ticket.

- Migration: jira_ticket_queue_items junction table
- POST /api/jira-tickets/:id/queue-items endpoint
- GET /api/ivanti/todo-queue/ticket-links endpoint
- ConsolidationModal component with aggregation logic
- IvantiTodoQueuePage with selection mode and ticket link badges
- Pure utility functions for summary/description generation
- 34 tests passing (backend + frontend)
