feat: add comprehensive REST API with token auth, OpenAPI docs, and full test coverage

- API token model (SHA-256 hashed, debounced lastUsedAt) with Bearer auth
- Dual auth middleware (session + API token) in src/lib/api-auth.ts
- 23 REST endpoints under /api/v1/ covering all functionality:
  tokens, proxy-hosts, l4-proxy-hosts, certificates, ca-certificates,
  client-certificates, access-lists, settings, instances, users,
  audit-log, caddy/apply
- OpenAPI 3.1 spec at /api/v1/openapi.json with fully typed schemas
- Swagger UI docs page at /api-docs in the dashboard
- API token management integrated into the Profile page
- Fix: next build now works under Node.js (bun:sqlite aliased to better-sqlite3)
- 89 new API route unit tests + 11 integration tests (592 total)
