Feat: update geometry logic on community stat api

[susilnem]

Changes

• Update the project update fields
• add new migration file to backfill geometry metadata from project GEOMETRY model.

Findings

Checked on the MapSwipe Backend Alpha 2 instance.

Projects with both centroid and aoi_geometry set to NULL

from django.db.models import Count

Project.objects.filter(
    centroid__isnull=True,
    aoi_geometry__isnull=True,
).values(
    "project_type",
).annotate(
    count=Count("id"),
).order_by("project_type")

Result:

[
    {'project_type': ProjectTypeEnum.FIND, 'count': 8},
    {'project_type': ProjectTypeEnum.VALIDATE, 'count': 21},
    {'project_type': ProjectTypeEnum.COMPARE, 'count': 1},
    {'project_type': ProjectTypeEnum.COMPLETENESS, 'count': 2},
    {'project_type': ProjectTypeEnum.STREET, 'count': 2},
    {'project_type': ProjectTypeEnum.VALIDATE_IMAGE, 'count': 19},
]

A total of 53 projects currently have both centroid and aoi_geometry set to NULL.

Project.objects.filter(
    centroid__isnull=True,
    aoi_geometry__isnull=True,
).count()

# 53

Projects with a populated centroid but missing aoi_geometry

Project.objects.filter(
    centroid__isnull=False,
    aoi_geometry__isnull=True,
).count()

# 0

There are no projects where the project-level centroid is populated while aoi_geometry is missing. In other words, whenever a project has a centroid value, it also has an associated aoi_geometry.
