[AZ-808] [AZ-809] [AZ-810] [AZ-811] [AZ-812] Cycle 8 close

Closes cycle 8 (Strict input validation across every public API
endpoint). After 4 batches, every JSON-body, multipart-envelope, and
query-parameter endpoint rejects unknown fields, missing required
axes, type mismatches, and business-rule violations BEFORE the
handler runs, all surfacing RFC 7807 ValidationProblemDetails per
error-shape.md v1.0.0.

Artifacts:

- cumulative_review_batches_01-04_cycle8_report.md
  PASS_WITH_WARNINGS. Cross-batch consistency check across all 5
  cycle-8 tasks: 0 Critical / 0 High / 0 Medium / 4 Low (all
  surfaced as per-batch findings; no NEW cumulative-only
  categories). 5 follow-up PBI candidates surfaced (test-helper
  consolidation, validator filter decision matrix in docs,
  RoutePointDto wire-shape unification, service-layer RouteValidator
  retirement decision).

- implementation_completeness_cycle8_report.md
  PASS. Every cycle-8 task promise is implemented as production
  behaviour. Production code verified for scaffold / placeholder /
  NotImplemented markers: none found in any cycle-8 validator. All
  five pipelines (region POST, lat/lon GET, route POST, upload
  POST, inventory POST) WIRED.

- implementation_report_strict_validation_cycle8.md
  Final cycle implementation report. 41 / 41 ACs covered across
  5 tasks (AZ-812, AZ-808, AZ-811, AZ-809, AZ-810). 63 new unit
  test methods + 52 new integration test methods + 4 new curl probe
  scripts + 3 new contract docs (region-request, tile-latlon,
  route-creation) + 1 contract version bump (uav-tile-upload
  v1.1.0 -> v1.2.0). Handoff to autodev Step 11 (Run Tests)
  documented.

Autodev state transitions Step 10 (Implement) -> Step 11 (Run Tests).
