fix: skip playerbots so bot re-rolls do not spam the server

PlayerbotFactory calls Player::GiveLevel() in six places while randomising a
bot, and GiveLevel fires OnPlayerLevelChanged exactly as a real ding does. On
a Playerbots realm that means every bot re-roll past level 10/20/.../80 sends
a server-wide broadcast plus a raid warning and hands the bot gold and two
reward items. Turning off CongratsPerLevel.Enable does not help: the
reward-level announcements sit outside that gate.

Adds Congrats.SkipBots (default 1). The bot test is guarded by
#ifdef MOD_PLAYERBOTS, which the core defines for every module when
mod-playerbots is present, so a core built without it is unaffected.

Also adds the missing `override` on OnPlayerLogin. The signature already
matched the base, so behaviour is unchanged -- it just stops a future
signature change from silently detaching the hook.
