Update learned facts

[d3vco]

Description

Ensures that learned facts are displayed for selection in the AddPotentialLinkModal

Current Behavior

In the current design, operations and sources are collect in the onMounted hook:

magma/src/components/operations/AddPotentialLinkModal.vue

Lines 102 to 114 in 32b5594

	onMounted(async () => {
	await agentStore.getAgents($api);
	if (agentStore.agents.length > 0 && canSelectAgent) {
	filters.agent = agentStore.agents[0];
	filters.executor = filters.agent.executors[0];
	} else {
	filters.agent = props.agent.paw;
	filters.executor = filters.agent.executors[0];
	}
	await abilityStore.getAbilities($api);
	await sourceStore.getSources($api);
	await operationStore.getFacts($api);
	});

And then later, these objects are used to collect the imported facts and learned facts:

magma/src/components/operations/AddPotentialLinkModal.vue

Lines 132 to 134 in 32b5594

	const opSource = sources.value.find((s) => s.id === props.operation.source.id);
	const opSourceCollected = sources.value.find((source) => source.name === props.operation.name);
	const facts = (opSource.facts.concat(opSourceCollected ? opSourceCollected.facts : [])).concat(operationStore.facts);

However, this design doesn't achieve the designed behavior because the AddPotentialLinkModal is only mounted once and then hidden/shown when the + Potential Link button is pressed. Therefore, the getFacts function is not called again and the learned facts are not updated.

New Behavior

The getFacts call is moved inside the selectedPotentialLink function, so it is called every time an ability is selected. This updates the facts array prior to displaying the screen where values can be selected.

Note 1: In this change, I also updated the sources that make up the facts. Previously, the facts were drawn from 3 sources:

1. The fact source associated with the operation (the source selected when creating the new operation)
2. The facts learned during the operation
3. The fact source generated by the operation

In this update I removed source 3 from the list above because this is a replica of sources 1 and 2 and causes all facts to be duplicated. If there is a reason to retain this feature, it can be re-added.

Note 2: The AddPotentialLinkModal retains the state of the last use of the modal. So if a user adds a Potential Link and then returns to the modal to add the same link again, the facts will not update unless the user goes back and re-selects the same ability.
