docs: fix stale keybindings, paths, and API examples

GETTING_STARTED.md:
- Fix keybinding table: T→N for talents, Q→L for quest log, W→M for
  world map, add missing keys (C, I, O, J, Y, K), remove nonexistent
  minimap toggle
- Fix extract_assets.ps1 example param (-WowDirectory → positional)
- Fix Data/ directory tree to match actual manifest layout
- Fix log path: ~/.wowee/logs/ → logs/wowee.log (local directory)

EXPANSION_GUIDE.md:
- Add Turtle WoW 1.17 to supported expansions
- Update code examples to use game_utils.hpp helpers
  (isActiveExpansion/isClassicLikeExpansion/isPreWotlk) instead of
  removed ExpansionProfile::getActive() and GameHandler::getInstance()
- Update packet parser references (WotLK is default in domain handlers,
  not a separate packet_parsers_wotlk.cpp file)
- Update references section with game_utils.hpp
