xpltd 43ddf43951 Purge intervals: hours→minutes, default ON at 1440min (24h)
- PurgeConfig: max_age_hours→max_age_minutes (default 1440)
- PurgeConfig: privacy_retention_hours→privacy_retention_minutes (default 1440)
- PurgeConfig: enabled default False→True
- PurgeConfig: cron default every minute (was daily 3am)
- Purge scheduler runs every minute for minute-granularity testing
- All API fields renamed: purge_max_age_minutes, privacy_retention_minutes
- Frontend admin panel inputs show minutes with updated labels

"""Persistent settings service — reads/writes the `config` table in SQLite.
Settings priority (highest wins):
1. Admin writes via UI → persisted in SQLite `config` table
2. Environment variables (MEDIARIP__*)
3. config.yaml
4. Hardcoded defaults
On startup, persisted settings are loaded and applied to the AppConfig.
Admin writes go to DB immediately and update the live config.
