BDMS-658: add location properties and contact summaries to well responses

[jirhiker]

Why

This PR addresses the following problem / context:

• The wells list and related thing responses exposed coordinates from the current location, but not the location metadata already stored on Location.
• The wells list also omitted associated contact summaries needed by the UI.
• The list response needed to include contact data without introducing N+1 queries.

How

Implementation summary - the following was changed / added / removed:

• Added county, state, and quad_name to GeoJSONProperties and populated them in LocationGeoJSONResponse.populate_fields.
• Added a compact contacts summary field to WellResponse with id, name, organization, contact_type, and role.
• Extended the existing well loader options to eagerly load contact_associations -> contact so the well list response can include contacts efficiently.
• Updated shared test fixtures and added focused response tests for the new location metadata and well-list contact summary.

Notes

Any special considerations, workarounds, or follow-up work to note?

• Validation run: pytest tests/test_thing.py -k "includes_location_properties or includes_contact_summary or details_payload or get_water_well_by_id_404_not_found or get_water_well_by_id_404_wrong_type or get_spring_by_id_404_not_found or get_spring_by_id_404_wrong_type"
• black passed on the touched files.
• flake8 on the touched files has an existing baseline of E501 and F403/F405; after removing the one new actionable warning from this change, targeted lint with those baseline rules ignored passed.
