fix(push): guard passive web push reconciliation

[Just-Insane]

Description

Guard passive web-push reconciliation on unsupported browsers and carry the related notification-restore fixes that were developed during the push investigation.

This branch:

• stops startup and foreground-resume reconciliation from entering the web-push registration path when PushManager is unavailable
• keeps supported web-push clients on the existing reconciliation path
• preserves /to/... notification restore behavior across hash-router and call-join deep links
• stabilizes notification-click room URL construction in the service worker

Related context: follow-up to the recent push recovery work that landed across PRs #116 and #117, and adjacent to the earlier unsupported-browser push fix in PR SableClient#868.

Set the matrix.to base before rendering descendants

When matrixToBaseUrl is configured, moving setMatrixToBase into a passive effect means RouterProvider and its children render once before the module global is updated. The matrix-to helper explicitly relies on this being set before any getMatrixTo* calls, and rendered hrefs such as forwarded-event links can stay on the default https://matrix.to/ until some unrelated re-render happens; previously the base was set synchronously before returning the children.

Skip redirect capture when the hash is absent

With hashRouter enabled, an unauthenticated user who lands on the bare origin without a # now passes the hash-router config into getAppPathFromWindowHref. getAppPathFromHref assumes a hash exists in that mode, so it slices the full URL as if it were a hash path and stores malformed after-login redirects like /https://host/ (or /ps://host/ with a basename), causing login completion to navigate to a bogus route instead of the normal landing page.
