test(infonet): cover gate directory renderer (landing + command variants) (#327)

Adds the focused test Codex wrote alongside the gate-directory UI work
that already shipped in #326 (the `renderGateDirectory` helper used
both under the Infonet logo on the landing screen and as the output of
the `gates` command in the terminal).

The renderer itself is already on origin/main; this PR just ships the
test so CI catches regressions to the dual-variant render.

Verified locally:
- frontend npm run test:ci -- src/__tests__/mesh/infonetShellGateDirectory.test.tsx → 1/1 pass
