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.
