The auto-sync overhaul added a [start, end] range and a shared numbering picker, but each mode's UI exposes only a subset of the persisted fields (Provider's "Start #" writes channel_numbering_fallback; Next Available exposes no Start/End) while the backend read auto_sync_channel_start and auto_sync_channel_end in every mode. Switching modes never resets the others, so a stale or auto-computed value silently changed numbering.
- Provider mode honors the provider-supplied number (stream_chno) verbatim; the group's Start (channel_numbering_fallback) and End bound only the fallback for streams the provider did not number. auto_sync_channel_start is no longer applied in provider mode.
- Next Available ignores End, since its UI exposes no range.
- Range enforcement (the overflow-delete) runs in fixed mode only, the one mode with a user-set [start, end] range.
- Provider mode gains the Start>End guard fixed mode already had, so an inverted fallback range cannot fail every numberless stream.
