feat: landing page with Download, SCP Pull, and Resume cards

- Hero header at top describing the app
- Two side-by-side cards: Download (URL) and SCP Pull
- Resume sessions section appears above cards when sessions exist
- Download card expands to inline form
- Resume asks for VM Name/ID only, skips URL field
- Clean separation of entry points
