Add player action logging for admin operations

Introduces a new addPlayerAction method in adminRepository and logPlayerAction in adminService to record admin actions on player accounts. Updates relevant admin routes to log actions such as bans, unbans, forced name changes, and skin resets. Also improves error messages in adminService for consistency and clarity.
