Cobblemon Secret Base Trainer

- Removed the Battle Clone skin URL download controls and client-side external skin download path, so custom clone skins now only come from local skin files and normal in-game skin syncing, due to a curseforge upload rejection issue.

- Reworked the Battle Clone config screen into a cleaner tabbed layout with improved spacing, grouping, rule toggles, and battle-format selection styling.
- Added `Random Walking` with a configurable radius, letting Battle Clones roam around their placed anchor point and return properly when turned off.
- Added clearer rule tooltips, improved AI difficulty coloring, and expanded config-screen localization across the Battle Clone UI.
- Added a global server config toggle for whether admins can edit other players’ Battle Clones, with server-side enforcement.
- Restyled the server config screen to match the newer config-screen look while keeping the mod’s brown theme.
