perf: quick wins for pipeline, jobs, httpapi and web ops

- CDN snapshot: batch merge после parallel fetch, без race на persist
- ListRevisionPrefixes: лёгкая проверка revision вместо GetRevision
- Jobs: timeout/cancel context для pipeline и deploy
- HTTP server timeouts; кэш birdc для GET /peers
- ListModules: batch DoH profiles одним запросом
- Web: tab-scoped load на /operations, debounce job search, меньше over-fetch на dashboard
