UX-08 2d review: action log reachable in status JSON, engaged peak row pinned, imported keys expanded

- status_payload() also returns the action log as `events`. The page
  does not render it. Some entries (a dropped inverter's reason, the peak
  guard's projection, unplaced watts) are written nowhere else, and DOCS
  still points installers at the action log.
- test_peakguard pins the engaged row's ordered pair (the battery's share,
  then the limit).
- test_messages expands setting keys named by constants imported from
  another app module, so the shown-text 30-word scan counts them.
- p1.py: 'A meter message could not be read'. DOCS glossary: control
  board in plain words, with the hardware in an installer note.
