* refactor: migrate admin icons to @makeplane/propel
Replace confirmed icon symbols in apps/admin with their audited
@makeplane/propel/icons targets, merging into the imports the six
already-migrated files declared. Unresolved symbols (Menu, BrainCog)
and the LucideIcon type stay on lucide-react.
Lucide size props become explicit width/height. Loader keeps its
LoaderIcon alias so the call site is unchanged.
apps/admin already declared @makeplane/propel, so no dependency change
was needed.
* fix: restore Settings breadcrumb label after icon rename
The migration's identifier rename also rewrote the string literal, so the
breadcrumb displayed the icon component name instead of the label.
