Juan José Mata d47aa2fe90 PWA offline error page + login page cleanup (#327) ...

* Add friendly PWA offline error page

When the PWA fails to connect to the server, users now see a branded
offline page with a friendly "technical difficulties" message, the
app logo, and a reload button. The page automatically attempts to
reload when connectivity is restored.

Changes:
- Created public/offline.html with branded offline experience
- Updated service worker to cache and serve offline page on network failures
- Added service worker registration in application.js
- Service worker now handles navigation requests with offline fallback

* Extract PWA offline logo to separate cached asset

Move the inline SVG logo from offline.html to a separate file at
public/logo-offline.svg. This makes the logo asset easily identifiable
and maintainable, as it may diverge from other logo versions in the future.

Changes:
- Created public/logo-offline.svg with the offline page logo
- Updated service worker to cache logo as part of OFFLINE_ASSETS array
- Updated fetch handler to serve cached offline assets
- Updated offline.html to reference logo file instead of inline SVG

* Update offline message for better readability
