The mesh API (routes/mesh.js) had zero UI -- minting a join token,
joining a remote gateway, or seeing what's meshed all required calling
the API directly. New Mesh page (nav: Dashboard/Sessions/WireGuard/
Mesh/Audit):
- This Gateway card: interface name, kernel-vs-userspace WireGuard mode
(wireguard-go fallback), meshed-gateway count.
- Mint a Join Token: calls POST /api/mesh/join-tokens, shows the
single-use token once.
- Join a Remote Gateway's Mesh: calls POST /api/mesh/join with a remote
endpoint + token.
- Meshed Gateways table: site, mesh index, mesh subnet, endpoint, public
key, last seen -- including this gateway's own self-entry.
EJS compile verified; jump-host's existing test suite (34 tests) still
passes. Not yet visually driven in a browser the way sso-manager-node's
modal was (jump-host's OIDC-based admin auth is a heavier lift to stand
up for a one-off check) -- route registration, EJS compilation, and the
API layer underneath are verified; the actual click-through is not.
