fs 476f688bd8 harden: web/index.php — runtime fingerprint, API channel isolation, extract() safety ...

Three robustness improvements to the request entry point:

P1a: Module runtime stale-detection via fingerprint
- ModuleRuntimePageBuilder gains writeFingerprint/readFingerprint/expectedFingerprint
- module-build.php writes storage/runtime/.module-fingerprint after each build
- web/index.php validates fingerprint on every request; throws RuntimeException
  with actionable message if stale (replaces silent auto-build in request path)
- Eliminates P2 (concurrency) by removing build from hot path entirely

P1b: API requests skip session/auth/cookie flows
- Channel detection (isApiRequest) moved before Session::start()
- Session::start(), remember-me, session timeout, tenant refresh and locale
  resolution wrapped in if-not-API guard
- API endpoints no longer set cookies or trigger login redirects
- Default locale set separately for API so t() works in error responses

P3: extract(Router::getParameters(), EXTR_SKIP)
- Prevents URL parameters from overwriting existing scope variables
