fix: tidy the phone layouts

- Wrap long code lines in the explorer below 992px; the declared
  useWrapMode option was never applied.
- Light editor and gutter use the page colour, like dark mode.
- New anonymization uses the same 18px inset as other pages.
- Settings, new conference and FAQ section links scroll in one row
  instead of wrapping under a lone underline.
- Page intros are no longer clamped to two lines.
- Status page actions stack full width without the anonymize form's
  sticky bar styling; dropdown labels no longer split apart.
