multi-module cleanup: daily logs, luaalloc enable, minimap texture fix

- logsessions: switch from timestamped per-session files to daily rotation
  (WoWCombatLog_YYYY_MM_DD.txt), remove path pointer overwrites, persist
  paths across logout so redirects keep working
- logging: add append file mode (openAppend) for daily log rotation
- minimapicons: clear texture binding after blip render to fix stale
  texture with Silicon d3d9 layer
- weirdperformance: enable luaalloc slab allocator (was disabled for testing)
- worldmarkers: extract FN_SET_UNIT_POSITION to offsets, use lua.typeOf
  helper, update doc comments for renamed API
- delete unused guidcache standalone test module
