- Appointments now carry a date; the Calendar button opens a Google-Calendar
style month grid (color-coded event chips, month nav, Today, click a day for
its list). Today/Upcoming sections derive from dates.
- Add-appointment dialog gains a date picker (Popover + Calendar).
- Messages rebuilt as chat threads: an input-based composer that appends to a
two-way timeline (no more toast covering the field), and the unread count is
now a filter toggle.
- Favicon: the brand logo now shows in the tab. Removed the stale default
app/favicon.ico (which shadowed it) and added app/icon.png + app/apple-icon.png
generated from the logo; dropped the redundant metadata.icons.
- Sidebar: swapped Notes <-> Messages order (both kept).
- New pages: Activity (signed-change audit timeline with hash chips + approval
status) and Tasks (two-pane care-team to-do with add dialog).
- Prescriptions: adding a medication now surfaces mock drug-interaction and
allergy warnings against the patient's record.
