Fix CI/CD: Update ratatui dependencies and ignore unmaintained paste warning

- Updated ratatui from 0.24 to 0.29 to get latest features
- Updated crossterm from 0.27 to 0.29 for compatibility
- Updated tui-input from 0.8 to 0.14
- Updated unicode-width from 0.1 to 0.2
- Fixed ratatui API changes:
  - Use Frame::area() instead of deprecated Frame::size()
  - Table::new() now requires widths as second parameter
  - Use row_highlight_style() instead of deprecated highlight_style()
- Added ignore for RUSTSEC-2024-0436 (paste unmaintained warning)
  - This is a transitive dependency through ratatui/tui-input
  - The crate still works fine, just not actively maintained
