feat: add Mint.com-inspired Terminal User Interface (TUI)

- Add interactive TUI with dashboard, transactions, budgets, and investments views
- Implement Mint-inspired dashboard with net worth, cash flow, and spending categories
- Add transaction browser with search and filtering capabilities
- Include visual progress bars and gauges for financial metrics
- Support keyboard navigation with Tab, arrow keys, and shortcuts
- Load ALL transactions (not just recent) for complete visibility
- Add comprehensive README documentation for TUI usage

The TUI provides a modern, visual way to interact with financial data
directly in the terminal, making it easy to browse transactions and
view financial summaries at a glance.
