fix(nav): restore Loan Origination and Investment menus dropped by merge

The "Merge dev into demo" commit silently dropped both top-level nav
entries (desktop and mobile variants) along with their entire menu
panels — Loan Origination's mat-menu and the whole Investment mega-menu
(~150 lines) — because dev never had these menus, so the merge picked
dev's shell.component.html wholesale for this file instead of combining
both sides' additions. The underlying feature modules and routes were
untouched, so this restores only the shell wiring, copied verbatim from
the pre-merge demo revision.
