Thomas Eizinger c93a3d710a fix(gui-client): don't panic during setup hook (#9112)
As part of launching the Tauri GUI client, we need to observe a specific
initialisation order. In particular, we need to wait until Tauri sends
us a `RunEvent::Ready` before we can initialise things like the tray
menu.

To make this more convenient, Tauri offers a so-called "setup hook" that
can be set on the app builder. Unfortunately, Tauri internally panics if
this provided setup-hook returns an `Err`. Removing this is tracked
upstream: https://github.com/tauri-apps/tauri/issues/12815.

Until this is fixed, we stop using this "setup hook" and instead spawn
our own task that performs this work. This task needs to wait until
Tauri is ready. To achieve that, we introduce an additional mpsc channel
that sends a notification every time we receive a `RunEvent::Ready`.
That should only happen once. We only read from the receiver once, which
is why we ignore the error on the sending side in case the receiver has
already been dropped.

Resolves: #9101
