Improve PF2e stat block action icons, triggers, and tag handling

- Replace unicode action cost chars with custom SVG icons (diamond
  with chevron for actions, outlined diamond for free, curved arrow
  for reaction) rendered inline via ActivityCost on TraitBlock
- Add activity icons to attacks (all Strikes default to single action)
- Add trigger/effect rendering for reaction abilities (bold labels)
- Fix nested tag stripping ({@b ...{@spell ...}...}) by looping
- Move icon after ability name to match AoN format
