Addresses Gitea suggestions #3 and #2.
#3 Mobile: the sidebar was desktop-only (hidden md:flex), leaving phones with no
nav at all. Added a slide-out drawer (hamburger in the top bar, md:hidden) that
reuses the nav. Lifted navItems/settingsItems into src/components/layout/nav-items.ts
so the sidebar and mobile drawer share one source + active-state logic. No HTTPS
needed (pure responsive UI).
#2 Suggestions: the @otm/account-panel SuggestionsPanel hardcodes light neutral-*
text that assumes a white backdrop, so it washed out on the app theme — now
rendered on a white card for contrast in light/dark. Added a lightbulb button in
the header that jumps to Suggestions (like FMB).
