feat: add PAT kill switch (#3454)

## Add the ability to disable Personal Access Tokens (PAT) admin API

This PR disables PAT admin endpoints so it's not possible to create or
get PATs the kill switch is enabled, the UI is hidden but the existing
PATs will continue to work if they were created before. The delete
endpoint still works allowing an admin to delete old PATs

By default the kill switch is disabled (i.e. PAT is enabled by default)
