Closes the coverage gap where existing bats suites would report green
on a node whose dashboard tiles 502 because the proxy upstream is dead.
First pass against .198 caught real prod issues immediately:
/app/lnd/ → 502 (lnd container exited)
/app/mempool/ → 502 (mempool container exited)
/app/fedimint/ → 502 (fedimint container exited)
while existing tests reported only "container is up: false" with no
404/502 distinction.
* lib/ui-probes.bash — sourced helper. probe_https_200,
probe_app_url (skip-if-container-down else assert-200),
probe_dashboard_shell (asserts the Vue SPA HTML, not nginx default —
catches the layout regression from feedback_release_tarball_layout.md),
probe_dashboard_catalog (asserts /catalog.json non-empty).
* bats/ui-coverage.bats — 9 @test cases covering the dashboard +
bitcoin-ui :8334 + the seven HTTPS_PROXY_PATHS most users hit
(lnd, electrumx, mempool, fedimint, btcpay, filebrowser).
URL list mirrors HTTPS_PROXY_PATHS in
neode-ui/src/views/appSession/appSessionConfig.ts. Divergence between
the two is the exact bug class we're guarding against.
Loops clean under run-20x.sh. Container-state oracle is via local
podman inspect, so the suite must run on the archy host (same as
companion-survives-archipelago-restart.bats).
