Add shareable QR payment system to rCart:
- PaymentRequestDoc schema with amountEditable support
- Payment API routes (create, list, get, update, QR SVG, Transak session)
- folk-payment-page: 3-tab payer view (Card/Wallet/EncryptID passkey)
- folk-payment-request: self-service QR generator with passkey auth
- Payments tab in folk-cart-shop for managing requests
- Extract Transak utils to shared/transak.ts (used by rFlows + rCart)
Routes: /:space/rcart/request (generator), /:space/rcart/pay/:id (payer)

Add Automerge schemas, lifecycle hooks (onInit, docSchemas), and
local-first client wrappers for all remaining PG modules:
rWork, rVote, rCal, rFiles, rCart, rBooks, rTrips, rInbox, rSplat, rFunds.
Each module now:
- Defines typed Automerge document schemas (schemas.ts)
- Registers docSchemas and onInit hook with SyncServer reference
- Moves initDB() from top-level to onInit for unified startup
- Has a client-side local-first wrapper (local-first-client.ts)
Dual-write route handlers will be wired incrementally per module
following the rNotes pattern established in Phase 2.
