fix: checkbox overlap in datatables

[KhushamBansal]

Notes for Reviewers

This fixes an issue where the sticky checkbox column was transparent, causing horizontal scroll text to overlap. Removed !important from MuiTableCell root background to allow MUIDataTableSelectCell to have a solid background, and added matching linear-gradient hover states.
