Phase 2: wire MPMB spell data in (XGtE/TCE + more sources)

The app loaded SRD-only spells; the parsed MPMB spell file was shallow (names only) and
unused. Now:
- parse_mpmb.py extracts the rich spell fields (level, school, casting time, range,
  components, duration, save, ritual, classes) and writes to src/data/srd.
- New compendium/mpmb.ts normalizes MPMB spells to the Open5e Spell shape (school/time
  expansion, source-code → label) — pure, unit-tested.
- loadSpells merges 204 non-SRD MPMB spells (95 XGtE, 21 TCE, + Eberron/Theros/Strixhaven/
  Fizban's/etc.) into the 321 SRD spells (525 total), deduped by name.
- Spell type gains a  field; the compendium spell list shows it ('Cantrip · XGtE')
  and adds a Source filter.

Verified in-app (Toll the Dead → 'Cantrip · XGtE'). 333 tests green, build OK.
Only mpmb-spells.json regenerated; feats/others untouched.
