Fix menu system crashes and stability issues

- Fix IrisSpotlight crash ($00F361): Removed errant $0116/$17 writes
  from menu_select_item.asm that corrupted VRAM upload index
- Fix journal stack corruption: Added missing PHB in Journal_CountUnlocked
- Fix P register mismatches: Added SEP #$30 to Menu_RefreshQuestScreen,
  Menu_ScrollFrom, Menu_DrawRingPrompt
- Fix MagicBag crashes: Fixed data bank corruption in error path,
  fixed uninitialized Y register in cursor movement
- Relocate StoryState from volatile $7C to SRAM $7EF39E
- Add bounds checking to HouseTag_Main jump table
- Use long addressing (.l) for SRAM access in custom_tag.asm
