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.

Replace ~3500L admin.js monolith with thin orchestrator (~700L) +
14 IIFE-wrapped per-section modules under /js/admin/sections/.
Section modules expose AdminSections.<name>.init/reload (lazy init via
switchTab/router) and re-expose onclick handlers via window.X for
backward compat. Shared helpers (MODES/DIFFS, fmtDate, pctClass,
renderMath, qTypeBadge, pagination) live in /js/admin/_shared.js
exposed on window.AdminCtx.
switchTab now dispatches to AdminSections via ROUTE_TO_SECTION map;
non-extracted system tabs (topics/audit/errors/health/classroom/avatars)
remain inline in admin.js. user-panel overlay markup untouched — Phase 6
will remove it.
