Polish sprint 1/2: restore crash fix, pf2e parity, full glyph purge

Crash fix:
- restoreBackup (file + cloud pull) now validates each row through its Zod
  schema, backfilling new fields — an older backup no longer lands characters
  missing feats/concentration/etc and crashing the sheet. + test.

pf2e parity (closing feature gaps vs 5e):
- +9 missing classes (Animist, Exemplar, Gunslinger, Inventor, Kineticist,
  Magus, Psychic, Summoner, Thaumaturge) with data + class tips.
- the wizard now enriches pf2e classes with their caster ability, so pf2e
  spellcasters get the Spells step + "Caster" tag like 5e.
- editable Perception rank and spellcasting proficiency on the pf2e sheet
  (fixes wrong initiative / spell DC at higher levels); rank-10 spell slots.
- pf2e monster resistances/weaknesses/immunities now apply in combat (flat
  amounts: resistance subtracts, weakness adds, 'all' matches any type). + tests.

Glyph purge (finishing the emoji→Lucide migration): replaced ~40 leftover
text-glyphs (✕ − + ✦ 🤫 ⬆ ⬇ ☑ ☐ ▶ ◀ ‹ › ★ ↻ ▸ ↑ ●) with Lucide icons across
Modal (every dialog), the sheet sections, dice, settings, player panels, world
pages, map editor, roll tray, and session UI.

Gate: 293 unit + e2e green; tsc + build clean.
