Update jq-repeat to 2.1.0; fix removed __setPut/__setTake API

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.
- update() is now trailing-edge throttled (~50ms) even on the first
  call, not just rapid subsequent ones -- no code in this repo reads
  DOM/item state immediately after calling update(), so no risk here
  (unlike sso-manager-node's companion PR, which needed a fix).
- jr-order-reverse and nested jq-repeat templates: not used anywhere
  in this repo.

Real breakage found and fixed: users.ejs/groups.ejs/permissions.ejs
called $.scope.X.__setPut(fn)/__setTake(fn) as setter METHODS -- that
API is gone in 2.1.0. Insert/remove hooks are now set via direct
property assignment ($.scope.X.__put = fn), per the current README.
Verified live (real dev server + Playwright): before the fix, all
three pages threw "__setTake is not a function" and the
insert/remove row animations were broken; after, zero errors and the
hooks fire correctly.
