v2026.9.2

Added

• Added the theme-aware Activity Rules sidebar with live condition results
  and a complete in-place draft editor for adding and editing activities.

Fixed

• Added server-owned validation, template previews, review diffs, and an
  explicit history-clear confirmation for destructive rule changes; browser
  code never mutates ConfigEntry data directly.
• Fixed the Activity Rules Review changes action, which was shadowed by a
  renderer method and therefore appeared to do nothing.
• Reordered custom state-condition fields to show match before state values and
  added explicit per-condition matched/not-matched status in the live tree.
• Added numeric_state conditions for decimal state or attribute thresholds
  (>, >=, <, <=, =, !=) with optional duration.

Changed

• Activity editing is now available only in the Activity Rules sidebar; the
  integration configuration page remains dedicated to initial setup.
• Changed the sidebar icon to mdi:clock-outline to match the clock-based
  integration artwork.
• Rule and midnight-policy edits now preserve retained summaries and keep an
  active session open until the new stop rule is actually satisfied.
• Added Copy rule, which opens a detached editable draft without creating
  an activity until it is explicitly saved.
