fix: updating application should check the context config

[miraclx]

Updating the application for a context should first submit it to the context config contract

Here's the relevant snippet:

core/crates/context/src/lib.rs

Lines 685 to 703 in f1ddc4c

	pub fn update_application_id(
	&self,
	context_id: ContextId,
	application_id: ApplicationId,
	) -> EyreResult<()> {
	let mut handle = self.store.handle();
	let key = ContextMetaKey::new(context_id);
	let Some(mut value) = handle.get(&key)? else {
	bail!("Context not found")
	};
	value.application = ApplicationMetaKey::new(application_id);
	handle.put(&key, &value)?;
	Ok(())
	}
