feat(modifiers): add Feruchemy, savant, metal supply, and combat modifiers

Add Feruchemy modifiers: keeper_of_terris, first_metalmind variants
for strength/memories/health. Add savant_power_surge for temporary
Allomantic flare. Add metal supply modifiers (abundant/low/depleted)
and atium_reserve. Add brutal_repression county modifier for skaa
uprising consequences. Fix county_opinion → county_opinion_add.

Add opinion modifiers: disappointed_opinion and
guilty_about_snapping_opinion for parent reactions to failed snapping.
