refactor: extract fallback textures, add why-comments, name WMO constant

Browse source 
- character_renderer: extract duplicated fallback texture creation
  (white/transparent/flat-normal) into createFallbackTextures() — was
  copy-pasted between initialize() and clear()
- wmo_renderer: replace magic 8192 with kMaxRetryTracked constant,
  add why-comment explaining the fallback-retry set cap (Dalaran has
  2000+ unique WMO groups)
- quest_handler: add why-comment on reqCount=0 fallback — escort/event
  quests can report kill credit without objective counts in query response
