```
csv_preview: Make horizontal scrollbar width respect pinned columns config (#57245)

## Data table: Add left inset for scrollbar alignment with pinned
columns

When pinned columns are enabled in the data table, the horizontal
scrollbar previously extended across the full table width, including
behind the pinned columns. This change adds a left inset to the
scrollbar so it only spans the scrollable area, properly aligning with
the content layout.

## Demo (look at bottom scrollbar)

### Changes

- Add `pinned_width()` and `scrollable_width()` helper methods to
`ResizableColumnsState` to compute column widths
- Refactor scrollbar rendering to use absolute positioning with inset
when pinned columns are present
- Scrollbar now correctly positions itself to span only the scrollable
(non-pinned) column area
