Replaces the old single `users.fcm_token_web` column, which held one token

|
for the whole account: signing in on a laptop overwrote the phone's token
|

|
|
and signing out anywhere cleared it for every device, so the phone silently

stopped receiving pushes.

The token is minted by the browser, not by us, and FCM returns the *same*

value for a given browser install regardless of who is signed in — hence the

|
unique constraint plus reassign-on-register in the repository, so a shared

browser moves its token to the new owner instead of delivering that user's
