Two follow-ups on the activity-row swipe work:
1. SwipeableRow now supports BOTH directions
----------------------------------------
The component grew a `leftActions` slot alongside the existing
right shelf. Drag the row right to pull the left shelf into view
(non-destructive action: Archive, Pause, etc.); drag left to pull
the right shelf into view (destructive: Delete). Past
REVEAL_THRESHOLD (60 px) the corresponding shelf locks open;
below it, snaps closed. Each shelf is opt-in — omit a slot and
the row only swipes one direction.
- `computeSwipeNext` and the new `snapPosition` helper take a
`{ leftActions, rightActions }` flag pair so the math knows
which directions are valid. Drags toward a missing shelf get
clamped to 0 instead of fully open.
- Activity rows wired as iOS-Mail-style: leading edge (right
swipe) = Archive/Restore (amber), trailing edge (left swipe)
= Delete (destructive red).
- Tests grew to 16 cases covering: snap-to-closed below threshold
either way, snap-to-open at/past threshold either way, clamps
don't escape the shelf width, missing-shelf rows don't snap to
a non-existent open state, baseOffset-aware reverse-drag math,
and SSR markup contracts (data-testid, data-state="closed",
translateX(0px), aria-hidden=true on closed shelves, no
orphaned shelf wrapper when only one slot is provided).
Also fixed a `-0` slip in the clamp branch (`-maxRight` is `-0`
when maxRight is 0) so call-site equality checks behave.
2. Reminders list rows are swipeable too
----------------------------------------
/reminders page now wraps each row in SwipeableRow:
- Left swipe → Delete (always available, destructive).
- Right swipe → Pause (when status is "active") OR Restart
(when "paused" or "ended"). Other lifecycle states (failed)
omit the right shelf entirely; the row only swipes one way.
Each shelf button is a tiny `<form>` posting to the existing
server action (delete / pause / restart) — no client-side state
beyond the swipe gesture. Page revalidates after the action,
list re-renders, row redraws in its new state.
Reused the same shelf-button visual language as the activity
tab (color-coded action, icon + label, dark-mode pairs) via a
tiny inline `ReminderShelfButton` helper.
