🐛: "Push Subscriptions" Garbage Pile-Up

[zvasilev]

What happened?

Implementing JMAP push against stalw.art.

Attached file is from JMAP Push get. All from one client(device).

It shows three problems:

1. Multiple duplicate deviceClientId.
   This ID (device + app + time) is supposed to be unique, so it should also be enforced as unique on the server.
   The JMAP entry doesn’t have a timestamp, making it impossible to determine which entry is valid for subscription checking.

2. There seems to be no cleanup process.
   Many entries have expired but remain in the system.

3. For the client UI, it would be better if, after a few retries (e.g., 30 seconds) to the JMAP proxy server, the entry disappears, indicating an error.
