feat: add new scanners, enhanced triage, findings refinement, and deployment tooling

- Add gitleaks secret detection, lint scanning (clippy/eslint/ruff), and LLM code review scanners
- Enhance LLM triage with multi-action support (confirm/downgrade/upgrade/dismiss),
  surrounding code context, and file-path classification confidence adjustment
- Add text search, column sorting, and bulk status update to findings dashboard
- Fix finding detail page status refresh and add developer feedback field
- Fix BSON DateTime deserialization across all models with shared serde helpers
- Add scan progress spinner with polling to repositories page
- Batch OSV.dev queries to avoid "Too many queries" errors
- Add gitleaks, semgrep, and ruff to Dockerfile.agent for deployment
