fix(mobile): address iPhone layout issues across rankings, detail, compare

- rankings: hide Type/Action columns on mobile so metric value stays visible;
  ensure filter selects and table wrapper stay within viewport
- school detail: add min-width:0 / max-width:100% containment so internal
  overflow-x wrappers actually clip rather than pushing the page wider;
  explicit line-height on Ofsted grade badges to fix glyph clipping
- compare: sticky first column on the Detailed Comparison table so the Year
  labels remain visible while horizontally scrolling school columns
- search: shorten placeholder to "School name or postcode" so it fits mobile
  input width
- globals: overflow-x:clip safety net on .main wrapper
