Replace the convoluted useAccountSession composable with a pinia store
that in addition allows for the consolidation of all session related
functions to grouped into one module.
Add allowedAccountTypes page metadata which the authenticated middleware
uses to further restrict the types of accounts that can access the page.
If the account type is insufficent to access the page it will return an
HTTP 403 Forbidden status, which is rendered using the error page.
If a user logs out from a device the expectation should be that device
no longer having any association with the user's account. Any existing
push notifications should thefore be removed on server. For this reason
tie push notifications to a session, and remove them when the session is
deleted.
Provide a basic account system with login and server side session store
identified by a cookie. Upon successful login a signed session cookie
is set by the server with the session stored on the server identifying
which account it is logged in as. The client uses a shared useFetch on
the session endpoint to identify if it's logged in and which account it
is logged in as, and refreshes this when loggin in or out.
