Add father/mother links to NPCs, derived from the relationships text

- Npc gains self-referencing father/mother (nullable, ON DELETE SET NULL);
  editable as dropdowns on the per-NPC form
- app:npc:link-parents parses "son/daughter/child of X [and Y]" from the
  Relationships / Notes column, resolves the names within the same family,
  and works out which parent is father vs mother from husband/wife/widow(er)
  and son/daughter/sister/brother cues (plus a small name-gender table for
  the few the text can't disambiguate). --dry-run / --force. 92/180 linked,
  none ambiguous.
- migrations now pin ENGINE=InnoDB - the local WAMP MariaDB defaults to
  MyISAM, which silently drops foreign keys
