Kyle Carberry 6afcc7b904 refactor(site): replace DiffRightPanel with generic tabbed RightPanel (#22633)
Replace the single-purpose DiffRightPanel with a generic RightPanel
component that supports tabs, drag-resize, drag-to-snap, and
drag-to-collapse-sidebar.

## Changes

- **New `RightPanel.tsx`**: generic tabbed panel with:
  - Drag handle with pointer capture for smooth resizing
  - Snap thresholds: drag past max → expand, drag below min → close
- Live sidebar collapse when dragging to the left viewport edge (and
reverses if dragged back)
  - Persisted width via localStorage
- `onVisualExpandedChange` callback so parent syncs sibling visibility
during drag (not just on pointer-up)
- **Deleted `DiffRightPanel.tsx`**
- **Updated `AgentDetail.tsx`**: uses `RightPanel` with `tabContent`
record, tracks `dragVisualExpanded` for live chat section hiding
- **Updated `FilesChangedPanel.tsx`**: removed border/background (now
handled by RightPanel wrapper)

## Drag behavior

| Gesture | Effect |
|---|---|
| Drag left past 70vw + 80px | Snap to expanded (fullscreen within
parent) |
| Drag right below 360px - 80px | Snap to closed |
| Drag to left viewport edge (<80px) | Collapse sidebar live |
| Drag back from left edge | Uncollapse sidebar live |
| Start expanded, drag right | Live resize back to normal |
