UX-13 P3 review: truthful peak lines, a clock-proof test, Simple stays default

- The peak limit's Why and plan block need a real power request (floor above
  0 W), not a blind or floor-limited guard. An Off battery gets the peak
  block only while it gives power. Why no longer says every battery gives.
- test_batteries_screen pins the fixture clock: unpinned it failed every
  morning. New checks cover the trade and cycle filters, the blind guard and
  an Off battery that A covers alone.
- Settings keeps only a picked view; a link to Installer is not remembered.
- Browser check: badges, unsaved change across views, locked value.
