Replace all sql.unsafe() calls with Automerge document operations
across rfunds, rbooks, rsplat, rnotes, rwork, rvote, rcal, rfiles,
rcart, rtrips, and rinbox. Only rforum retains PG (Discourse provisioning).
Each module now uses _syncServer.getDoc/changeDoc/setDoc for all CRUD,
with ensureDoc() helpers for lazy document creation. Schema SQL files
archived to .sql.archived. Adds Automerge round-trip test suite (35 tests).
