fix: pin price column to right edge of row (v0.13.4)

Root cause: .ab-mp-price and .ab-mp-ctx were siblings in .ab-mp-row-meta
with price first. Description text is variable-length, so the meta div
grew/shrank per row, shifting the price left/right.

Fix:
- Move price to last child in .ab-mp-row-meta so its right edge is
  always pinned to the row's fixed right edge
- Add flex-shrink: 0 to .ab-mp-price so it never compresses
- Cap .ab-mp-ctx at max-width 200px with text-overflow: ellipsis
- Swap column header order (Context, then Price) to match new DOM order

+- Model picker price column now consistently right-aligned. Root cause: price and description were siblings inside .ab-mp-row-meta, with description first and variable-length — this shifted price left/right per row. Fix: moved price to last position with flex-shrink: 0 so its right edge is always pinned to the row edge; capped description at max-width 200px with ellipsis; swapped column headers to match new DOM order.
