[v10.1.x] Auth: Refactor for revoking user tokens within last hours (#74820)

Auth: Refactor for revoking user tokens within last hours (#74616)

* fix: revoked tokens within last hours

adds check for unlimited sessions out of index
adds a function for specifing the hours to look back when revoking users tokens, otherwise we "assume" the clean up takes care of them adds a index for the `user_auth_token` - `revoked_at` for faster queries when using `revoked_at`

* fix: sqllite datetime conversion with unixtimestamps

* fix: postgres dialect

* fix: mysql dialect

* fix: mysql dialect missing closing )

* refactor: delete revoked tokens directly

* fix: tests for sqlite

* AuthToken: Simplify DeleteUserRevokedTokens and add test

* fix: linting newline

* Reset get time after test

* fix: test order by revoked

* fix: order by different db

* ascending

* test with seen at
