fix(culture): restrict traditions to appropriate cultures and remove dead params

Fix tradition can_pick conditions so each is culture-specific:
- tradition_noble_intrigue: restricted to noble_scadrian
- tradition_skaa_resilience: restricted to skaa
- tradition_terris_scholarship: restricted to terris
- tradition_allomantic_heritage: kept as heritage_scadrial (all)

Remove dead parameters blocks (allomantic_potential_bonus,
noble_intrigue_bonus, skaa_resilience_bonus, terris_scholarship_bonus)
that were never referenced by any scripted triggers.
