feat: redesign landing page and add demo.rcal.online subdomain

Replace the minimal landing page with a full rStack-style marketing page
featuring hero with gradient text, 4-card principles grid, feature pillars,
temporal zoom visualization, four-view showcase, ecosystem integration
cards, and CTA section.

Move the calendar app to /demo route served at demo.rcal.online via
middleware subdomain routing. Add per-route layouts for Header placement
so the landing page controls its own chrome.

Also includes AppSwitcher/EcosystemFooter category reorganization
(rTube/rSwag to Creating, Social & Media split into Sharing + Observing).
