Add server/scripts/migrate-encryption.ts — a standalone script that
re-encrypts all at-rest secrets (OIDC client secret, SMTP password,
Maps/OpenWeather/Immich API keys, MFA secrets) when rotating
ENCRYPTION_KEY, without requiring the app to be running.
- Prompts for old and new keys interactively; input is never echoed,
handles copy-pasted keys correctly via a shared readline interface
with a line queue to prevent race conditions on piped/pasted input
- Creates a timestamped DB backup before any changes
- Idempotent: detects already-migrated values by trying the new key
- Exits non-zero and retains the backup if any field fails
README updates:
- Add .env setup step (openssl rand -hex 32) before the Docker Compose
snippet so ENCRYPTION_KEY is set before first start
- Add ENCRYPTION_KEY to the docker run one-liner
- Add "Rotating the Encryption Key" section documenting the script,
the docker exec command, and the upgrade path via ./data/.jwt_secret
