Replaces the
unloadevent withpagehidefor sending disconnect beacon from the Blazor client to the server.The two should fire in (practically) the same situations but
pagehideis not deprecated and does not cause warnings for the users.More fundamental improvements for the circuit cleanup scenarios will be done in later PRs.
Fixes #54793
