Update jq-repeat to 2.1.0; fix editProfile update->slideDown race

jq-repeat 2.1.0 (release notes: https://github.com/wmantly/jq-repeat/releases/tag/v2.1.0)
brings real fixes (throttled-update race conditions, sorted-list
reverse() leaking elements, nested-scope isolation) and a few
behavior changes. Audited every usage in this repo against the
changelog before upgrading:

- push()/unshift() now return the new array length -- every call
  site in this repo is a bare statement, none consume the return
  value. No risk.
- __setPut/__setTake, jr-order-reverse, nested jq-repeat templates:
  not used anywhere in this repo (unlike proxy's companion PR, which
  needed the __setPut/__setTake fix).

Real risk found and fixed: update() is now trailing-edge throttled
(~50ms) even on the first call, not just rapid subsequent ones.
profile.ejs's editUser()/editUserSeccess() call $.scope.editProfile
.update()/renderProfile() (which itself calls update()) and
immediately slideDown() the same element -- with the old synchronous
behavior the form was already populated by then; with throttling it
could briefly show stale/empty data. Deferred both slideUp/slideDown
pairs by 60ms (past the throttle window), per the library's own
migration guidance. Verified live (real bundled image + Playwright,
logged in as admin): the edit form's fields show real data, not
empty/stale, when checked right as the slide-open completes.
