fix(channels): make edit/delete actions use parent context after bottom sheet closes

Browse Source 
Root cause: edit/delete dialogs were opened from the sheet context after Navigator.pop, so context.mounted was false and follow-up actions never ran.

Also keeps async await/error handling for channel edit/delete so failures surface to users instead of silently dropping.
