Split NPC page: read-only detail + game notes, separate full edit form

- /npcs/{id} (app_npc_show): portrait, all fields shown read-only, and
  the only editable control is the game-notes textarea. Father/Mother
  link through to their own pages.
- /npcs/{id}/edit (app_npc_edit): the full structured form, now WITHOUT
  game notes; saving returns to the detail page.
- NpcType drops gameNotes; new NpcGameNotesType holds just that field.
- The DataTable row link (/npcs/{id}) now lands on the detail page.
