Guard against MyPlayer being nullptr in IsPlayerDead(),
CycleSpellHotkeys(), RefreshTownNpcOrder(), SpeakSelectedTownNpc(), and
ListTownNpcsKeyPressed() to prevent crashes during early init or after
disconnect. Also reset AutoWalkTrackerTargetId when MyPlayer is null in
the auto-walk tracker to prevent the walk loop from retrying endlessly.

The variable is only used within tracker.cpp, so remove the unnecessary
extern declaration from the header and place it in the anonymous
namespace alongside the other file-local tracker state.

Move ~4,100 lines of accessibility code from diablo.cpp into 6 new
modules, reducing diablo.cpp from ~7,700 to ~3,660 lines.
New modules:
- controls/accessibility_keys: UI key handlers and guard functions
(IsPlayerDead, IsGameRunning, CanPlayerTakeAction, etc.)
- utils/walk_path_speech: BFS pathfinding, PosOk variants, walk
direction helpers, and path-to-speech formatting
- utils/accessibility_announcements: periodic announcements for low
HP warning sound, durability, boss health, monsters, doors
- controls/town_npc_nav: town NPC selection cycling and auto-walk
- utils/navigation_speech: exit/stairs/portal/unexplored speech and
keyboard walk key handlers
- controls/tracker: target category cycling, candidate finding,
pathfinding navigation, and auto-walk tracker
