add hybrid calculator refactor and comprehensive billing test suite

Move planner financial model from client-side JS to server-side Python
(calculator.py + /planner/calculate endpoint). Add full test coverage:
227 calculator tests and 371 billing tests covering SQL helpers,
webhooks, routes, and subscription gating with Hypothesis fuzzing.
