Improve search indexation lifecycle

[jacomyal]

The main issue lies here:

gephi-lite/packages/gephi-lite/src/core/graph/index.ts

Lines 526 to 529 in 1e4e890

	// When graph data or fields changed, we reindex it for the search
	if (updatedKeys.has("fullGraph") || updatedKeys.has("edgeFields") || updatedKeys.has("nodeFields")) {
	searchActions.indexAll();
	}

Basically, there are way too many cases where we reindex everything rather than doing incremental indexation. Here are two examples:

• When an edge direction changes (it makes the fullGraph reference change)
• When we change the label of an attribute
