feat: CLIN-3507 manage add and update note and list variants with notes

[meek0]

No new routes

Create: previous properties will be merged with newer one (if previous exists)
Filter: can filter note with either true or false e.g. /variants/filter?note=true to get ids with non null note

Si tu utilise le await pas besoin du then, je l'écrirais plutôt sous cette forme:

Suggested change

	}).then(async function onResponse(value: VariantModel) {
	const variantFound = await VariantModel.findOne({
	order: [['timestamp', 'DESC']],
	where: {
	unique_id: {
	[Op.eq]: uniqueId,
	},
	author_id: {
	[Op.eq]: authorId,
	},
	},
	});
	const variantCreated = await VariantModel.create({
	unique_id: uniqueId,
	organization_id: organizationId,
	author_id: authorId,
	properties: {
	...(variantFound?.properties || {}),
	...properties,
	},
	timestamp: new Date(),
	});
	return variantCreated;
