Assign investments to headings based on their location

[javierm]

Background

In pull request, #3907, we added the possibility to assign a geozone to a heading and make it appear on a budget's map.

On the other hand, when creating a new investment project, citizens can select which heading the project is associated to and the location of the investment on a map.

This might lead to inconsistencies, since a project might belong to a heading while being displayed on an area belonging to a different heading.

Objectives

Note: this is a draft. The problem is a complex one and we haven't found a solution yet; so what follows are just ideas.

It would be great if, when choosing a place on the map, the project was assigned automatically to a heading. However, there are some potential problems: what happens if the selected area doesn't belong to a heading? What happens if the heading isn't associated to a geozone? What happens if there are many headings associated to the same geozone?

Here is a not-so-good idea as detecting the Scope of operation automatically, but at least it reduces the chance to enter inconsistent information through the interface 🤔 .

• The user goes to the new budget investment form
• When the user changes de "Scope of operation", the map loads just the limits (polygon) for the selected option
• The user only can add a marker if it's placed within the geozone limits
• Maybe we can write a server-side validator to verify the coordinates are within the geozone limits. No idea about how complex this is at this time.
