nook: show the full feature set on the landing page

The landing page sold eight features from around 0.6 and summed up the
rest in one line, while 0.6–0.10 shipped most of the island's modules. It
also said twelve agents (Muse made thirteen) and marked phone approvals
"coming soon" although the iPhone companion is in TestFlight beta.

Adds live demos for terminal replies, the volume mixer, Capture with its
Wings, and floating actions; a bento of module tiles behind a two-way
feature marquee; and an iPhone/Watch beta section whose request form
posts the same email-only report the app's Settings > Phone card sends.
The approval flow, remote sessions and setup, timer, temperatures and
Capture mocks are rebuilt from the app's own views, so the site shows
what the island actually draws.

Tests: report.test.ts pins the landing page's beta request against the
/report schema (red when the schema demands a machine snapshot); nook and
subdomain suites pass.
