Addresses code review: differentiate pool_scrub_line/1 FINISHED clause
with the word "finished", test the degraded-vdev callout via a second
DEGRADED pool in the fixture, and replace the generic "scrub" match
with an assertion on the full finished line.
New design language:
- dark background, system sans for UI, monospace for data
- single green accent, amber/red for warn/critical
- square-bordered panels + tables, no rounded cards or shadows
- status conveyed via left-border on overview cards + badges
Changes:
- new app.css defines CSS vars + component classes (.panel, .tbl,
.card, .btn, .input, .badge with [data-status=*])
- new ServerWeb.DashboardNav function component for a shared top nav
with active-link highlighting; replaces per-view navigation clutter
- strip the Phoenix welcome scaffold (logo, version badge, twitter/GH
links) from layouts/app.html.heex; leaves only flash + content
- root.html.heex title suffix switched to 'Proxmox Monitor', body
loses the Tailwind-white background
- rewrite render/1 in all four LiveViews + login template to use the
new classes; admin form now uses <.form for={@form}> and properly
clears on success
- login page redesigned to a single tight panel matching the rest
All 58 tests still pass; 'mix compile --warnings-as-errors' is clean.
Returns 200 with {status: ok, version, db: ok} when SQLite is reachable,
503 when the DB probe fails. Unauthenticated so external monitors can
poll without credentials.
Extended Server.Release with migrate/0 and rollback/2 so
'bin/server eval Server.Release.migrate' works from a released binary.
Removed the phx.gen.release-generated rel/overlays/bin/server wrapper
that hardcoded 'start' — it collided with the mix-release default
dispatcher, blocking 'server version', 'server eval', etc. The 'migrate'
overlay is kept (bin/migrate calls server eval under the hood).
Application.start ran mark_all_offline unconditionally, which meant
every "mix run"/"mix ecto.migrate" invocation would flip all
connected hosts to offline. Gate the call on Phoenix.Endpoint.server?
so non-serving boots don't disturb live state.
