Submit task form on Enter in title field

[dkhalife]

When in the add/edit task screen on the Android app, pressing Enter (Done IME action) while focused on the task name field now submits the form, matching the Save button's behavior and respecting the same disabled state (blank title or saving in progress).

Pull request overview

Updates the Android task add/edit screen so pressing the IME “Done” action while focused on the title field submits the form, matching the Save button behavior (including disabled conditions).

Changes:

• Extracted form submission logic into a shared submitForm() lambda guarded by canSubmit.
• Wired the title OutlinedTextField IME action (ImeAction.Done) to trigger submission via KeyboardActions(onDone = ...).
• Reused the same submit path for the Save button click handler.
