access: overhaul tracker keybindings in InitKeymapActions

Replace 7 individual navigation/tracker key registrations with 3 unified
tracker keys: PageUp (previous), PageDown (next), Home (navigate/walk).
Unbind legacy town NPC nav keys (now superseded by tracker Npcs category).
Update health key description to mention Shift+mana.
