Move ingestion + Telegram/Bale/Divar config to DB-backed admin settings

- AppSetting gains source config: AutoIngestEnabled, IngestIntervalMinutes, Telegram/Bale/Divar enabled+channels/token/queries
- IListingSource.FetchAsync(AppSetting) — sources read config from DB, not IOptions/appsettings; sample source dev-only
- IngestionWorker reads AutoIngest+interval from DB each cycle (toggle at runtime, no redeploy)
- /Admin/Settings gets a 'منابع جمع‌آوری' section; removed Ingestion env/appsettings + compose env vars
- ENV_FILE shrinks to HOST_PORT + POSTGRES_* + ADMIN_PHONE (AI + sources are all in-admin); migration
