Carlos Escalante c725c1487d Add pytest harness and 55-test suite for core backend logic ...

Covers: billing-cycle characterization (the BE-06 convention, boundary
instants, year wraps, deferred transactions), projection engine
(recurring schedules, no-double-count, cumulative balances, overrides,
fresh start), auth (JWT roundtrip/expiry, API tokens, constant-time
creds, rate-limit window), fail-fast settings, and the BAC paste
parser. SQLite in-memory fixtures, exchange rates pinned — no network.
Also doubles as the float-behavior baseline for the Phase 2 Decimal
migration (plan 1.5). config.py moves to SettingsConfigDict to clear
the pydantic deprecation warning from test output.
