fix(chat,analysis,sidebar): compact cards, sparse citations, range + active state

- Chat patient cards are now compact previews (header + key stat + "Click for
  more"); cards size to content (items-start) instead of stretching to the tallest;
  Edit record moved into the summary detail dialog
- AI citations render once per source per message (collapses per-word spam) and the
  prompt now asks the model to cite sparingly (once per paragraph, not per list item)
- Sidebar sub-items use exact-match active state so Meetings no longer lights Inbox
- Analysis defaults to All Time, drops the 12m option, and clamps the chart window
  to >=2 points so 30d/Today render instead of collapsing
