Review: Bump django-filter 25.1 → 26.1

Overview: Routine Dependabot dependency bump in requirements/base.txt — single-line version change, no code changes required elsewhere.

Compatibility check

• django-filter 25.2 dropped support for Django < 5.2 LTS and Python 3.9. This repo pins django==5.2.16 (requirements/base.txt) and builds on Python 3.12.7 (compose/local/django/Dockerfile, compose/production/django/Dockerfile), so both floors are comfortably cleared.
• 26.1 only adds test coverage for Django 6.1 / Python 3.14 — no breaking API changes noted in the changelog for the version range this repo uses.
• django-filter appears in exactly one requirements file (requirements/base.txt), so there's nothing else to keep in sync.

Risk / correctness

• No FilterSet/filter-backend code in this repo appears to depend on removed/changed behavior between 25.1 and 26.1 based on the changelog excerpt in the PR description (only CI/test-matrix and locale-file changes are listed for the intermediate 25.2/26.1 releases).
• Low blast radius: this only affects DRF/GraphQL filtering behavior if any endpoints use django-filter FilterSets — worth a quick CI run to confirm no filter-related tests regress, but no manual code review action needed beyond that.

Recommendation

Safe to merge once CI passes. No test coverage changes needed since this is a transitive dependency bump with no application code touched.
