[UI] Mouse Drag-and-Drop for Tab Reordering and Panel Resizing

[yashksaini-coder]

Goal

Bring modern TUI interaction with mouse drag support.

Description

Implement mouse drag event handling in src/ui/input.rs:

1. Tab reordering: Detect a mouse press-and-drag on the tab bar. Track the drag position and swap tab order when released over a different tab slot.
2. Panel resizing: Detect a drag on the border between the package list and details pane. Update a split_ratio: f32 field in App (e.g., default 0.5) that the layout in draw.rs uses for the Constraint::Percentage split.

Crossterm provides MouseEventKind::Drag and MouseButton — enable mouse capture with crossterm::event::EnableMouseCapture.

Note: Mouse support in terminals is optional and varies — always maintain full keyboard fallback functionality.
