utf8mb4_uca1400_ai_ci (MariaDB-only) breaks bootstrap on MySQL, where
CREATE DATABASE/CREATE TABLE fails outright. Switch the shared playerbot
schema and bootstrapped tables to utf8mb4_general_ci, matching the rest
of the playerbot_v2 migrations.
The LEFT JOIN characters.characters cross-DB qualifier hardcoded the
characters schema name, breaking installs with a renamed characters
database. Read it from CharacterDatabase.GetConnectionInfo() (worldserver.conf
CharacterDatabaseInfo) instead, falling back to 'characters'.
- ConfigReader: add PlayerbotsV2.FleetBots switch (default 0) + fleet_bots() accessor
- Module::Init/OnWorldUpdate: skip population shaper, bot guilds, craft-order
board, BG/LFG queue auto-fill, and AutoResume/AutoSpawn when fleet disabled
- Services: FleetThread is not started in alt-bot-only mode
- conf/playerbot.conf.dist + README document the new key
