Subject: [PATCH] fix: defer state updates in receive screen dispose to avoid
 widget tree lock

Wraps clearTipping(), updateMessage(), and updateListenerAmount() calls in
addPostFrameCallback during dispose() to prevent "setState() or
markNeedsBuild() called when widget tree was locked" error.

These methods trigger notifyListeners() which cannot be called during the
dispose phase. Deferring them until after the current frame ensures the
widget tree is unlocked before state updates occur.
