Per the intended model: catalog sources should live in the config place (like
domains), and registry_catalog.json should be a purely GENERATED artifact
derived from them — not the source of truth. Replaces the earlier
$docker_dir/catalog/sources.json store.
- New configs/general/general_catalogs — CFG_CATALOG_1..9, one catalog base URL
per slot ("url" or "url|channel"), domains-style. Official stays pinned as
source #1 (derived from CFG_RELEASE_BASE_URL, not listed here). Slot N → source
idx N+1 (stable id for the Add picker / `app add --source`).
- catalog_sources.sh now reads/writes those CFG vars (via updateConfigOption)
instead of a JSON file; dropped catalogSourcesFile + the enable/disable toggle
(presence = enabled; remove = clear the slot).
- configUpdateBatch regenerates registry_catalog.json when a CFG_CATALOG_* key
changed — so pressing Save in the WebUI rebuilds the browse data.
- webuiRegistryCatalogScan is unchanged (still iterates catalogEnabledSources).
Verified: CFG_CATALOG_1/2 → sources at idx 2/3, empty slots skipped, url|channel
parsed, official pinned at idx 1.
