Phase 1 foundation: backend, web profile, and mobile app

Greenfield implementation of CardClaws Phase 1 across three surfaces.

Backend (Rust/Axum workspace, 67 tests):
- cardclaws-types/config/db/auth/api/wallet crates
- Auth: register, login + lockout, magic link, refresh rotation, Apple verify
- Cards: CRUD, tier-limited publish, duplicate, public handle lookup
- Assets: R2 presigned uploads; vCard export
- Apple Wallet .pkpass pipeline (PKCS#7 signer behind apple-signing feature)
- Analytics ingest + summary with daily-salted IP hashing
- Migrations 0001 (incl. cardclaws_sessions) + 0002 analytics

Web profile (Astro SSR): cardclaws.com/[handle] hero + flip, contact actions,
client-built vCard, visit attribution. Verified end-to-end.

Mobile (Expo SDK 51): auth, card list/create, builder v1 (bg/text/logo,
palette, undo/redo), Skia/Reanimated viewer (flip + ambient). 22 logic tests.

CI: policy/backend/profile/mobile jobs; LOC + no-placeholder lint.

Review fixes baked in: `back` (not `cardclaws`) key; strip image is a bundled
manifest file (not a URL); sessions table added; NFC reframed; test doubles
allowed for external services.
