Add PF2e spell description popovers in stat blocks

Clicking a spell name in a PF2e creature's stat block now opens a
popover (desktop) or bottom sheet (mobile) showing full spell details:
description, traits, rank, range, target, area, duration, defense,
action cost icons, and heightening rules. All data is sourced from
the embedded Foundry VTT spell items already in the bestiary cache.

- Add SpellReference type replacing bare string spell arrays
- Extract full spell data in pf2e-bestiary-adapter (description,
  traits, traditions, range, target, area, duration, defense,
  action cost, heightening, overlays)
- Strip inline heightening text from descriptions to avoid duplication
- Bold save outcome labels (Critical Success/Failure) in descriptions
- Bump DB_VERSION to 6 for cache invalidation
- Add useSwipeToDismissDown hook for mobile bottom sheet
- Portal popover to document.body to escape transformed ancestors
