Tests for INDL-48 — Public "Find a Loved One" & "Plot Availability" endpoints.

Covers functional correctness for the new/enhanced public endpoints:
  - GET  /api/public/records            (year bounds, interment_type, sort,
                                          section_code, memorial_slug, limit cap)
  - POST /api/public/records/ai-search  (validation, plan gate, 501, mocked
                                          Claude extraction, prompt-injection
                                          containment)
  - GET  /api/public/plot-types
  - GET  /api/public/plots/available    (section_id/section_code/plot_type_id,
                                          price filters, price bound validation)
  - GET  /api/public/plots/stats        (established_year)
  - GET  /api/public/sections?vacant_only=true

...and the INDL-48 PRD Security Acceptance Criteria that are testable at the
API/unit level: SEC-02, SEC-03, SEC-05, SEC-06, SEC-09, SEC-12, S-01, S-02,
S-04, S-05, S-06, S-08. See the bottom of the file for a criterion-by-criterion
index docstring.

Conventions follow the existing files in this directory (test_records_search.py,
test_sections_and_plot_stats.py): tenant resolved via `X-Tenant-ID` header,
`db_session` fixture for direct ORM setup, `client` fixture for the ASGI test
client, `test_account` fixture for the default (starter-plan) tenant.
