feat: native comments, bug reports, dictionary, type safety (#200)

* feat: native comments, bug reports, word dictionary, and type safety overhaul

Comments system:
- Replace Giscus (GitHub Discussions) with native comment section on word pages
- Comments table in Postgres (shared with bug reports via type field)
- Real-time game result badges via single SQL query with correlated subquery
- Badge rules: N/maxGuesses for wordle modes, N guesses for semantic, skip speed
- Mode label only shown when user has 2+ badges for the same word
- Basic moderation: profanity filter, URL blocking, rate limiting, hidden flag
- Flat list, auth required to post, public to read

Bug reports & feedback:
- In-app report modal replacing GitHub Issues link in sidebar
- Reports stored in comments table (type='report'/'feedback')
- Auto-collects URL, browser, screen size, PWA status, language, mode
- Optional email notification via Resend (works without it)

Word page improvements:
- WordDictionary: full Wiktionary entries (senses, etymology, IPA, forms)
- WordTranslations: cross-language word links with SSR-safe language names
- Fix hydration mismatch: translations now use server-resolved names instead
  of client-side cache (useNuxtData), eliminating 80+ hydration warnings that
  were corrupting Vue's component tree and breaking teleports/event handlers
- Fix @unhead/vue dispose crash: merge 3 useHead/useSeoMeta calls into 1
- JSON-LD enriched with pronunciation and etymology from kaikki data
- Image handling moved from HEAD-probe to server-provided image_url

Type safety (45 errors → 0):
- Add type annotations to all implicit-any parameters across server utils
- Extend UiStrings and LanguageHelp types with missing optional properties
- Fix null vs undefined mismatches in Vue components
- Fix Nuxt route type recursion (ofetch import bypasses typed $fetch)
- Add trackCustomEvent to analytics composable
- Fix semantic.vue notification, game complete params, and compass types
- Add TargetNeighbor model to Prisma schema (was orphaned, 4.4M rows)

Passkey auth improvements (LoginModal rewrite):
- Multi-step flow: main → passkey choice → register/authenticate
- Platform-aware ordering (passkey first on iOS, Google first elsewhere)
- Email sign-in placeholder

Other:
- Dictionary import script (scripts/import_dictionary.py)
- Gitignore: design/, kaikki_processed/, public exploration files
- TODO: leaderboard comments, comment admin tooling, Resend setup

* style: format with Prettier + fix ruff lint errors
