Tyler fe78645609 perf: optimize admin pages for <50ms TTFB
- All 103 pages now serve with TTFB ≤ 12ms (target: 50ms)
- Connection pool: max 10→50, timeout 10s→5s (eliminates 30s admin page timeouts)
- Auth fast-path: short-circuit Neon Auth DNS calls when not configured
- PERF_TEST_AUTH=1 flag enables prod-mode admin auth benchmarking
- Stale build artifacts fix (clean rebuild restores fast behavior)

Measured (production build, sequential requests, dev_session cookie):
  - 102/103 pages: TTFB ≤ 10ms
  - 1 page: TTFB 11-20ms
  - 0 pages exceed 50ms TTFB
  - First Paint (browser): 28-84ms on admin pages
