Add v4 property column stats API

[nllong]

Any background context you want to provide?

Inventory has a summary page which showed the count of entries in each field. More stats would be useful to really understand what data are in a SEED org's inventory.

What's this PR do?

• remove v4/analyses which wasn't related to analysis, but was analyzing the data in the inventory.
• created new column_summary endpoint on the v4 property endpoint

This PR currently includes updated from the fix-migrations PR #5261

How should this be manually tested?

Launch with SEED-platform/seed-angular#70 and go to inventory summary.

What are the relevant tickets?

Pull request overview

This PR replaces the v4 analyses stats endpoint with a new v4 properties/column_summary endpoint that returns richer per-column inventory statistics (including numeric aggregates, distribution stats, and unit metadata), and incorporates the referenced migration/order-determinism fixes.

Changes:

• Removed v4/analyses and added v4/properties with a new column_summary action for column-level stats (including optional raw data).
• Added deterministic tie-break ordering (id) to several “latest/ordered” queries to prevent nondeterministic results on timestamp ties.
• Added/updated repair migrations to restore missing PK/unique constraints for production DBs; updated Angular static-file serving fallback paths.

Fixed in commit where _build_property_views_queryset now accepts an AccessLevelInstance object directly (instead of fetching by ID), and the instance is fetched once before the cycle loop in column_summary.
