fix(fusion_clock): portal white-border + responsive timesheet entries

- White border on every portal page: the .fclk-app full-bleed relied on exact
  negative margins to cancel the portal layout's container padding; when it
  didn't match, the white page chrome showed through. Match the PAGE background
  to the app (light #f3f4f6 / dark #0f1117, via body:has(.fclk-app)) so the
  gutter is invisible, and clip horizontal overflow.
- Timesheets not responsive: the 6-column table crammed/wrapped on phones.
  Replaced the table with stacked cards (date + net up top, in -> out, then
  break / location / Correct) that read cleanly at any width. Correction-link
  data attributes preserved; the xpath-inherited .fclk-nav-bar untouched.

Live on entech 19.0.3.12.2 (both rules verified in the served frontend bundle).
