feat: 1.5.0 prep — API v1 cutover, LICENSE, CHANGELOG, CI

- Remove legacy /api/ mount; all routes now under /api/v1/ only
- Update path matchers (CSRF excludes, public routes, audit log, rate limits)
- Move standalone routes (/api/network/ips, /api/docs, /api/docs/spec) to v1
- Update openapi.yaml (110 paths), CA pages, and 4 lingering frontend files
- Add LICENSE (proprietary EULA), CHANGELOG.md (Keep a Changelog format)
- Add .gitea/workflows/ci.yml (test+lint and security audit jobs)
- Fix 9 pre-existing no-empty lint errors so CI starts green
- Drop ad-hoc scratch reports and *.bak files from repo root

All 739 jest tests pass. Lint is clean.
