Wire up restartUnits on secrets whose consumers cache them in memory
(daemons read at startup), so sops-nix restarts the affected unit on
activation when the decrypted content changes:
- firefly: app_key → phpfpm-firefly-iii;
auto_import_secret + access_token → phpfpm-firefly-iii-data-importer
- searx: secret_key → uwsgi
- opencode: web password → opencode-serve
- mail: sasl_passwd → postfix
- forgejo: gitea_dbpass → forgejo; runner-token → gitea-runner-default
Secrets read on demand by oneshots/timers (firefly sparda_pin, ntfy
token, restic backup creds, acme dns creds, wg conf) are left as-is.
