feat: add memo filter and enhance description filter with regex matching

- Add new memo filter to transaction page (searches :transaction/memo)
- Enhance existing description filter to use case-insensitive regex
- Both filters support wildcard matching via .* pattern
- Add e2e tests for filter functionality
- Update test data with memo fields
