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.
we were only deleting channels and messages on device and the in app db would persist
this caused weird messages to later show up in other channels as they were deleted and
added due to the fact we store messages by channel index(slot #)

formats all dart files using `dart format .` from the root project dir
this makes the code style repeatable by new contributors and makes PR review easier
The second critical bug was in the validation logic that checks whether responses from the device contain valid data. The validator was rejecting any interval values of zero because it checked interval > 0, but zero is now a meaningful and valid value that indicates advertisements are disabled. Without this fix, any time a device reported back that advertisements were disabled, the app would silently discard that information as invalid, leaving the UI out of sync with reality. We changed the validation to use interval >= 0 instead and updated the comment to explicitly document that zero means disabled.
The third fix was a minor code style issue where a single-line if statement was missing braces, causing a linter warning. This doesn't affect functionality but ensures the code meets project standards.
- Reduce reaction payload from ~44 bytes to 9 bytes (5x smaller)
