feat(admin): Phase 6 sub-commit 2 — remove .user-panel overlay

Now that the deep pages (sub-commit 1) work, retire the legacy
.user-panel inline overlay entirely.

* admin.html: removed <div class="user-panel" id="user-panel"> block
  inside #tab-users, removed dead .user-panel* CSS (kept .btn-close
  for any external use).
* users.js: removed openUserPanel / closeUserPanel / reloadUserPanel
  and their closure state (activeTr, activeUserRole). User row onclick
  switched from openUserPanel(...) → AdminRouter.navigate('#users/N').
  clearUserHistory / toggleBanUser / confirmDeleteUser / openEditUserModal
  / openUserPermsModal / doSet/doReset* all refactored to use the
  getActiveUid() helper (reads window.activeUid, set by user-detail.init)
  + reloadDetailAndList() helper (refreshes deep page + list together).
* sessions.js: row click + eye-button switched from toggleDrawer(id)
  → gotoSession(id) → AdminRouter.navigate('#sessions/N'). Removed
  toggleDrawer + renderDrawer functions (~60L) and openDrawerId state.
  Inline drawer markup removed from the row template.

Verified node --check on all touched JS. ast-index confirms zero
remaining usages of openUserPanel / closeUserPanel / reloadUserPanel /
toggleDrawer across the repo.

This completes Phase 6 and the admin-redesign feature.
