Cleanup unused deployment secrets & args (#2698)

## Description:

* Remove unused otel creds
* Remove unused R2 creds
* remove left-over BASIC_AUTH
* Generate an admin token on startup
* Removed kick_player since lobby creators already have ability to kick
player

## 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:
