feat: Warm Industrial UI redesign + social footer + code deduplication

Design System (Phase A):
- New palette: warm charcoal #111110 / amber gold #c9954a / sage green #7a9a8a
- Fonts: Cabinet Grotesk (heading) + Geist (body) + JetBrains Mono (data)
- SVG grain texture overlay, collapsed sidebar with hover expand
- Bento grid dashboard with WideContinueCard + PosterCard + QuickLink
- Backward-compatible CSS aliases for glass-panel/neon-button/input-base

Social Footer (Phase B):
- AppFooter component with GitHub repo / author homepage / TG group links
- Embedded in LoginPage, Layout (global), and SettingsPage
- TG group badge added to README.md

Code Cleanup:
- Removed deprecated DownloadClientCard / NotifyChannelCard components
- Merged downloadClient/notify API clients into unified modules
- Route deduplication: removed authed-group duplicates for admin endpoints
- Removed redundant AdminPage tabs (sites/downloads/notify/scheduler)
- UI fixes: blank pages (discover/download-clients/notify-channels) nil slice defense
- Email channel support in NotifyChannelsPage
