ci: resolve CI failures in type check, codegen, and lint (#64)

* fix: resolve CI failures in type check, codegen, and lint

- Add missing title and artist fields to frontend QueueTrack interface
- Rename queue.QueueTrack to queue.Track and queue.QueueState to
  queue.State to fix revive stutter lint errors
- Fix wsl violations (cuddled declaration, block ending with comment)
- Break long slog lines to satisfy golines formatter
- Run go mod tidy to add missing go.sum entries for templ dependencies
- Regenerate sqlc output for updated tooling version

* fix(ci): disable redundant checkout in govulncheck action

The govulncheck-action runs its own actions/checkout internally,
which conflicts with the checkout@v6 already performed by the job.
This causes 'Duplicate header: Authorization' HTTP 400 errors.
Setting repo-checkout: false skips the redundant checkout.
