Fix forecast chart bar order and snapshot month derivation

Flip stacked bar chart so non-compliant (orange) renders on top and
compliant (blue) on bottom for better visual emphasis.

Use the file's report_date for compliance_snapshots month instead of
the current date, so historical uploads land in the correct monthly
bucket. Also fix rollback to delete the correct month's snapshot.

Remove cve-frontend systemd service ( Express serves theredundant
built frontend on port 3001).
