Cleanup: pf2e subclasses + all native dialogs → themed Modals

- pf2e classes now show the defining 1st-level choice (instinct / doctrine /
  bloodline / mystery / racket / implement / thesis / …) in the wizard's
  subclass picker, like 5e. Curated PF2E_SUBCLASSES in pf2e/progression.ts,
  merged into the class during the wizard's pf2e enrich step.
- replaced every remaining native dialog with a themed Modal:
  - PlayerView session-password prompt → password Modal
  - Settings cloud-conflict confirm → "Use cloud / Keep this device" Modal
  - SessionControl host-password prompt → host Modal (optional password)
  - MapEditor text-label prompt → label Modal (captures the click point)
  No window.confirm / window.prompt / window.alert remain in the app.

Realtime e2e updated for the host Modal (Host → Start hosting).
Gate: 293 unit + 35 e2e + 2 realtime; tsc + app/server build clean.
