Simplify modal, badge, and remaining component styles to dark-first

Remove all dark: prefix pairs across modals, badges, and 20 remaining
components. Simplify EncounterMethodBadge, ConditionBadge, and
RuleBadges to dark-only color values. Replace stray text-gray-400/500
with theme tokens (text-tertiary/secondary). Replace blue-600 accent
colors with theme accent tokens in modals and interactive elements.
