Fixes DB admin ranks being 16 bits wide instead of 24 (#89348)

## About The Pull Request
smallint is 2 bytes, increased it to mediumint which is 3 bytes
Issue has not cropped up yet as theres only 15 flags right now, but
there can be up to 24 in dm side soooo

```
DEBUG-SQL: MySqlError { ERROR 1264 (22003): Out of range value for column 'flags' at row 1 } | Query used: INSERT INTO admin_ranks
 - (rank, flags, exclude_flags, can_edit_flags)
```


my mysql is broken so I havent tested the update query but how bad can
it be :clueless:
## Changelog
