cursor[bot] 60c44fc48a [MM-70153] Fix error when deleting the only remaining channel permission rule (#37899)
* [MM-70153] Fix error deleting the only remaining channel permission rule

Deleting the last permission rule in a channel's Permissions Policy tab
left the channel policy with no rules and no imports, which the server
rejects with "Unable to save access control policy." Mirror the
Membership Policy tab and delete the channel policy instead when the
resulting policy would be empty, returning the channel to standard access.

* [MM-70153] Add tests for removing the last channel permission rule

Covers deleting the empty channel policy on save, preserving a remaining
membership rule, and surfacing a non-404 delete failure.

* [MM-70153] Cover 404-as-success and imports-present branches

Add tests confirming a 404 delete is treated as success and that a policy
with remaining imports is saved rather than deleted when the last
permission rule is removed.

* [MM-70153] Reset originalActive after empty channel policy delete

After deleting an emptied channel policy, clear the stale active flag so
a subsequent save in the same tab session does not re-enable membership
auto-sync. Mirrors the Membership Policy tab empty-delete path.
