feat(tests): Add transaction rules test suite with 8 passing tests

Add comprehensive tests for the SSR admin transaction rules module:
- Rule matching by description pattern
- Rule matching returns empty for no matches
- Validation accepts valid data with 100% account allocation
- Validation rejects invalid account totals
- Rule matching by amount range
- Rule matching by bank account
- Security tests for non-admin access
- Execute validation tests

All 8 tests passing with 9 assertions. Tests focus on the unique
rule matching engine functionality that differentiates transaction
rules from other admin modules.

Includes implementation plan documenting 23 test scenarios
and 6-phase approach for complete coverage.
