fix: footer translation, mobile search bar and table row layout

- Footer: use translate('built_on') key instead of hardcoded 'Built on';
  update fr.json 'built_on' → 'Basé sur Overleaf'
- Mobile project list: move search bar + button outside the bordered
  TableContainer so its width is viewport-constrained, not affected by
  the table's fixed layout
- Mobile table rows: use width:100% (not auto) on cells so they fill the
  full tr width regardless of the higher-specificity column percentage
  rules; add explicit width:100% on tr to anchor flex-column sizing;
  keep width:auto on absolutely-positioned actions cell
