The /api/connection-pool/health endpoint hardcoded a keepalive interval
of 15s while the pool actually uses 45s, so it reported a false value.
The endpoint now reads the live keepAliveInterval field. A startup
backoff comment that claimed jitter is also corrected; the backoff has
no jitter.
StartHealthChecking's goroutine captures startupProbe=true and blocks on
readinessChan until the readiness probe completes. WaitForBackendReady only
closed readinessChan on SUCCESS; on timeout it returned an error without
closing it.
main proceeds anyway after a timeout ('Staring proxy anyway'), so the
health-check goroutine stayed blocked forever on readinessChan: periodic
checks never began and bhm.IsHealthy() stayed false permanently, so the
backend could never be marked healthy again even after it recovered.
Release readinessChan on the timeout path too (via sync.Once for safety),
so the health-check goroutine proceeds to periodic checking.
Test: TestHealthChecksStartAfterStartupTimeout (after WaitForBackendReady
times out, readinessChan is closed).
* chore(security,refactor): extract sanitization and improve code quality

- [x] Add admin API authentication security warning
- [x] Extract WebSocket and stats streaming constants
- [x] Add best-effort error handling comments for resource cleanup
- [x] Expand sensitive field patterns for improved PII redaction
- [x] Simplify safety checks and remove redundant nil validations
- [x] Improve test coverage for password field redaction patterns
* refactor: replace interface{} with any type alias
- [x] Replace all `map[string]interface{}` with `map[string]any`
- [x] Replace all `interface{}` with `any` in function signatures and type definitions
- [x] Update sync.Pool New function returns from `interface{}` to `any`
- [x] Add package documentation comments to 8 package files
