## Responsive fixes

- Kept the page shell anchored with `flex-1 min-w-0` so child table layouts can shrink inside the content area.
- Moved shared DataTable scrolling to a native `w-full overflow-x-auto` wrapper so only the table region scrolls horizontally.
- Standardized table sizing around `Table className="min-w-full"` in shared DataTable and report tables.
- Updated shared toolbar text filters to use `w-full max-w-sm` instead of fixed responsive widths.
- Updated Employee Directory search input to use `w-full max-w-sm`.
- Updated pagination layout to wrap and stay inside its container on narrow screens.

## Overflow fixes

- Added `overflow-hidden` protection to report table cards.
- Prevented page-level overflow by keeping DataTable containers `min-w-0 max-w-full overflow-hidden`.
- Reduced forced table expansion by removing global `whitespace-nowrap` from table cells.
- Fixed Training Records certificate preview column to a stable `w-20 h-20` footprint so it does not push the table wider than necessary.

## Manual regression checklist

- Verify the dashboard page itself does not scroll horizontally on mobile widths.
- Verify only the table region scrolls horizontally when columns exceed available width.
- Verify Training Records pagination remains fully visible at small widths.
- Verify Pending Review filters and pagination stay inside the card/container.
- Verify Employee Directory search and filters wrap cleanly without clipping.
- Verify Users table and pagination stay inside the content area.
- Verify Reports table cards scroll only inside the table wrapper.
- Verify pinned action columns still render correctly after shared DataTable wrapper changes.
- Verify certificate previews still open the dialog and render thumbnail images correctly.
