feat(fips): SSH-over-mesh toggle + manifest-driven package metadata

fips/ssh_mesh.rs owns the 90-ssh.nft drop-in lifecycle: off by default,
any-peer scope behind the UI's danger confirmation or an explicit mesh
address list, reconciled on every daemon config install. The scanner now
takes installed apps' icons from their real manifest metadata (Cuprate's
Services tile) and classifies manifest-declared UI apps as launchable
even when the address probe misses (Alby Hub).
