New outbound-finance module that issues invoices to clients. M1 scope:
- types, constants, collections with demo seed (not auto-loaded)
- module.config registered in module-registry
- Dexie v27 with invoices / invoiceClients / invoiceSettings tables
- encryption registry entries for all three tables (type-safe via entry<T>)
- app entry (requiredTier: alpha) + gradient icon (emerald→teal, QR corner)
- route /invoices mounts ListView with empty state
Money stored as integers in minor units (Rappen/cents) to avoid float
drift. Totals kept plaintext for liveQuery aggregation; lines encrypted
as a whole array so titles ride alongside. Settings is a singleton with
stable sentinel id so sync dedupes on it.
Plan: docs/plans/invoices-module.md. Next: M2 CRUD + number generator.
