feat: TPW item upsert support

[LautaroPetaccio]

This PR adds TPW item upsert support.

[LautaroPetaccio]

Should we allow third party items to be created with a null urn_suffix?
These are the two alternatives:

• We could consider that any TWP item upsert MUST have an urn where we will get the suffix from. This implies that the form to create the new items must contain a new field to set the URN.
• We could allow any TPW item upsert to have its URN as null, and let the user set it later.

We talked about this a bit, but I think I'd go with option 1. Items MUST have an urn_suffix. Maybe we could just pre-fill it with the uuid to avoid having to add a new input to the Modal in the front-end

Great work

You could use isTPCollection here. Is not necessary, but with the change on the return type here you can remove the ! below later

[nicosantangelo]

Don't you think it's a bit weird to receive both types of items here? It's not clear why one it's being used for the spread and the other for the created_at itself.

Given that the method is just being used in one place, what do you think of simplifying it a bit. For example:

updateModelDates(createdAt?: Date) {
  const currentDate = new Date()
  return {
      created_at: created_at || currentDate,
      updated_at: currentDate,
  }
}

item = { ...item, ...this.updateModelDates(dbItem?.created_at) }

with this implementation (just one of many) the method could be useful for other Models aswell

[nicosantangelo]

After we merge this we could add a check for isTPCollection here and avoid having to use ! everywhere later on

[nicosantangelo]

Suggested change

	throw new Error('The given item URN is not TWP compliant')
	throw new Error('The given item URN is not TPW compliant')

(or just TP)

[nicosantangelo]

this could be using isTPCollection right?
