A user browser may rotate a user subscription endpoint/keys
anytime.
Currently, Discourse will receive a 4XX response while trying to
deliver a push notification and silently unsubscribe the device.
With this change, we will gracefully handle desativating the old
subscription and the replacement creation with the need for the user
to resubscribe manually every time it breaks.

To prevent opaque cache files, now all the CDN files will be requested in 'cors' mode if the cdn_cors_enabled global setting is enabled. Before enabling the setting, should enable the cors in the CDN server by adding the response header `access-control-allow-origin: *` or `access-control-allow-origin: https://discourse.example.com.`
And other external file requests other than CDN will not be cached if the response type is opaque.
This reverts commit e3de45359f.
We need to improve out strategy by adding a cache breaker with this change ... some assets on CDNs and clients may have incorrect CORS headers which can cause stuff to break.
Only restricting cache per age wasn't enough for instances with lots of
multimedia usage and high number of posts.
MaxEntries is also more effective on cleanup, and purgeOnQuotaError
advertise that Discourse cache can be purged if necessary.

The special offline page with fetch interception in service worker
is only strongly required on Android ad a pre-req for PWAs
This is now strongly restricted only to Android while iOS PWA support
gets better
Long term if we build offline support we can unlock it more globally
* Feature: Push notifications for Android
Notification config for desktop and mobile are merged.
Desktop notifications stay as they are for desktop views.
If mobile mode, push notifications are enabled.
Added push notification subscriptions in their own table, rather than through
custom fields.
Notification banner prompts appear for both mobile and desktop when enabled.
