Bump to v1.4.0 and document the local all-offline baseline

The footer version is the honest check that a deploy landed, so cut
1.4.0 for the Storage table.

Also record something that has now cost two sessions: the dev machine
isn't on the media stack's network, so every service is offline and the
live-poll endpoints 500 on a timer. That's the normal local baseline,
not a regression. Notes the monkey-patch pattern for exercising a card's
real rendering, plus the two traps that go with it — Jinja's auto_reload
follows app.debug (off), so template edits need a restart rather than a
browser reload, and LOGIN_PASSWORD has to be set explicitly.

+**Expect every service to be offline on the dev machine, and expect
+`/api/*` polls to 500.** The dev laptop is not on the network with the
+media stack, so Sonarr/Radarr/SABnzbd/Tautulli/Prowlarr/Ombi all refuse
+the connection: every card renders its `service_error()` state, the
+header pills all read "offline", and the browser console fills with
+`500` responses from the live-poll endpoints (`/api/sabnzbd` and
+`/api/tautulli` poll on a timer, so they repeat every few seconds).
+**This is the normal local baseline, not a regression** — don't go
+debugging it, and don't "fix" it. If you need to check whether a 500 is
+genuinely yours, stash the working tree and confirm the same response on
+a clean checkout.
+
+Because of that, the only reliable way to exercise a card's real
+(non-error) rendering locally is to monkey-patch its fetcher and run the
+app on a spare port, e.g.:
+
+```bash
+LOGIN_PASSWORD=test python3 -c "
+import app as a
+a.get_unraid_stats = lambda: {'status': 'ok', 'source': 'api', ...}
+a.app.run(host='127.0.0.1', port=5099)"
+```
+
+Two gotchas when doing this: Jinja's `auto_reload` follows `app.debug`,
+which is off, so **template edits need a server restart** — a browser
+reload alone will silently serve the cached template. And the login
+password comes from `LOGIN_PASSWORD`, so set it explicitly rather than
+hunting for the real one.
