Startup already removes orphaned rows from `character_achievement` (LoadCompletedAchievements), but `character_achievement_progress` rows whose criteria no longer exists in Achievement_Criteria.dbc were only deleted lazily, one character at a time, when the owning character logs in (AchievementMgr::LoadFromDB). Rows belonging to dormant characters therefore persisted indefinitely. Add AchievementGlobalMgr::CleanupOrphanedCriteriaProgress(), called once at startup right after LoadCompletedAchievements, which deletes progress rows for any criteria id no longer present in the criteria store. Same lookup and log wording as the existing per-character purge; no-op when nothing is orphaned.

Paired with mangostwo/server#238 and billy1arm/MangosFour-M3#2 (same fix across the WotLK/MoP-M3 forks).
Adds a global, unconditional startup purge of orphaned
character_achievement_progressrows (criteria no longer present in DBC), mirroring the existing completed-achievement purge.Startup already drops orphaned completed achievements in
LoadCompletedAchievements()(a nonexistentachievementid is deleted for all characters). Progress rows had no equivalent: an invalidcriteriawas removed only lazily, per-character, when an affected character logs in (AchievementMgr::LoadFromDB). Orphaned progress rows belonging to characters that never log in therefore persisted indefinitely.New
AchievementGlobalMgr::CleanupOrphanedCriteriaProgress()runs once at startup, right afterLoadCompletedAchievements()(criteria/DBC stores are already loaded by then):SELECT DISTINCT criteria, validate each againstsAchievementCriteriaStore, delete invalid ones for all characters. No-op when the table is empty or nothing is orphaned; same log wording as the existing per-character purge. Code-only, no schema change.Note (separate, not addressed here):
CharacterDatabaseCleaner— which had the only other global progress purge — never runs on any core, because nothing ever setscleaning_flagsinsaved_variables(schema-default 0, only ever read and reset). That's a latent design question (what should set the flags) worth its own discussion.This change is
