Merge: regla permanente de secretos (anti-filtración)

Nueva regla del operador (2026-10-31): los ficheros de secretos solo se
inspeccionan con herramientas que no muestran valores (jq keys, grep -c,
stat). Prohibido cat/grep -r sobre .env y volcar errores con DSN.

- tests/test_no_credential_patterns.py: 3 tests — DSN con credencial
  literal fuera de placeholders, nsec bech32 versionado, tokens hex de
  64 chars fuera de tests/.
- scripts/check-credential-leaks.sh: hook que falla si journald
  reciente contiene DSN con contraseña o nsec (redactando el valor en
  la salida). Sin timer propio (no autorizado); ejecutar manual o desde
  cron del operador.

Contexto: la rotación del rol hardcap y el DSN filtrado a journald por
el test del gate (corregido; la credencial filtrada ya está rotada).
