Delete character from app after successful HCE transfer to VitalWear watch

Browse Source 
When sending a character to the VitalWear watch via HCE, the transfer
is atomic (single NFC interaction). The character was being left in the
app after transfer, allowing it to be cloned indefinitely.

Delete the character from the database immediately after sendCharacterToWatch
succeeds, matching the behavior of physical bracelet transfers which delete
the character once both write phases complete.
