feat(frontend): Enhance transactions page with advanced filtering and UI improvements.

- Fix amount range filters (min/max) connection to API parameters
- Add enhanced quick date filters: "This week", "This year" alongside existing options
- Create skeleton loading components (TransactionSkeleton, FiltersSkeleton) to replace simple spinner
- Add running balance column with toggle functionality for both desktop and mobile views
- Consolidate TransactionsList.tsx and TransactionsTable.tsx into single comprehensive component
- Improve UI design with better visual hierarchy, spacing, and responsive layout
- Add proper TypeScript types and fix linting issues
