improve game websockt (re)connection (#2584)

Previously, the connection and reconnection logic were identical in
Worker.ts, so clients would need to be re-authorized for cosmetics etc
even when reconnecting. Now, on reconnect, Worker.ts only does
authentication - verifying the jwt is valid.

This will allow clients to require a valid turnstile token when first
connecting, and not when reconnecting after a broken ws connection.

## Please complete the following:

- [x] I have added screenshots for all UI updates
- [x] I process any text displayed to the user through translateText()
and I've added it to the en.json file
- [x] I have added relevant tests to the test directory
- [x] I confirm I have thoroughly tested these changes and take full
responsibility for any bugs introduced

## Please put your Discord username so you can be contacted if a bug or
regression is found:
