feat(deps): sprinkle @formkit/auto-animate on rail lists

Adds smooth fade+slide animations when list items enter/leave on the
three highest-visibility realtime surfaces:

- alert-rail.tsx — socket-driven alerts appearing / dismissed.
- my-reminders-rail.tsx — reminders completed / arriving via realtime.
- notes-list.tsx — notes added / edited / deleted.

One-line `useAutoAnimate()` hook per site, no CSS, ~2kb gzip. Replaces
the jarring "row just appears/disappears" pattern with a per-item
transition.

Skipped on pipeline-board (kanban) — combining auto-animate with
@dnd-kit's SortableContext causes double-animation glitches because
both libraries fight to animate the same layout shift.

Verified: tsc clean, vitest 1293/1293 pass.
