"""API key authentication.
Klucz przyjmowany z header `X-API-Key` lub `Authorization: Bearer <key>`.
Gdy `settings.api_keys` jest puste — auth jest wyłączony (dev mode).
Dodatkowo (anti-tamper): gdy `ALLOWED_APP_SIG_HASH` jest ustawione, każdy request
musi zawierać `X-App-Signature` z SHA256 (hex) signing certu APK. Mismatch → 403.
Re-packaging APK innym keystorem (debug → release) wykryty natychmiast.
