Swap vendored AdminLTE 2.4.18 + Bootstrap 3.4.1 for AdminLTE 4.1.0 +
Bootstrap 5.3.8 (AdminLTE's dist CSS now bundles Bootstrap, so the
separate Bootstrap stylesheet is dropped; only its JS bundle remains).
Rewrite the page shell (header, header_authenticated, sidebar, footer)
to AdminLTE 4's app-wrapper/app-header/app-sidebar/app-main/app-content
structure and nav-sidebar/nav-treeview markup, and convert the dashboard
(index.lp) box/small-box markup to Bootstrap 5 cards as the first fully
migrated page.
Verified against a live container: fixed a chart.js tooltip lookup that
still targeted the old .box selector, restored the header logo mini/full
swap and sidebar user-panel collapse behavior that AdminLTE 2 used to
provide for free, and resolved a duplicate id="navigation" collision
with AdminLTE 4's own accessibility skip-link script.
Every other page still uses the old box/Bootstrap-3-grid/BS3-plugin
markup and will render incorrectly until the remaining migration phases
land.
