904b3f1d61 fix: add SQLite compatibility for Decimal types
SQLite doesn't support Decimal natively - it stores DECIMAL columns as
REAL (float). This caused sqlite3.ProgrammingError when writing Decimal
values.

Changes:
- Add prepare_for_db() helper to convert Decimal→float before writes
- Add Pydantic validators to convert float→Decimal on model creation
- Update CRUD layer tests to verify float params for SQLite
- Add SQLite round-trip tests to verify precision is preserved

The data flow is now:
Decimal (calculations) → float (prepare_for_db) → SQLite → float → Decimal (validators)

d245047487 test: add CRUD layer tests with mocked database
Tests verify Decimal values flow correctly through CRUD operations:
- create_deposit passes Decimal amount to db.execute()
- create_dca_payment passes Decimal fiat and exchange_rate
- create_lamassu_transaction passes all 5 Decimal fields
- get_client_balance_summary returns Decimal types

41 tests now pass (23 unit + 18 integration).

49dd4d1844 test: add integration tests for CSV parsing and full distribution flow
Tests verify the complete data flow:
- CSV parsing → Decimal conversion (simulates execute_ssh_query)
- Commission calculations with parsed Decimal values
- Distribution calculations with 2 and 4 client scenarios
- Pydantic model creation with Decimal types
- Exchange rate precision and round-trip accuracy

Uses real Lamassu transaction data (8.75%, 5.5% commission rates,
discounts, multiple client configurations).

37 tests now pass (23 unit + 14 integration).
