[AZ-408] [AZ-410] [AZ-411] Batch 69: synth injectors + FT-P-02/03/14

AZ-408 (3pt) — Replace AZ-406 injector scaffolds with concrete generators:
- outlier.py: deterministic stride + far-away tile replacement; AC-2 ≥350m offset
- blackout_spoof.py: paired video blackout + FC GPS spoof with ≤40ms alignment;
  AC-4 realistic fix_type/hdop; AC-NEW-8 200-500m inter-spoof deltas
- multi_segment.py: ≥3 disjoint windows, ≥30s gaps, ≤25% coverage
- fc_proxy.py: timed-splice runtime proxy with pre-activate RuntimeError guard
- _common.py: derive_rng + tile-manifest reader + tmpfs helpers
- injector_fixtures.py: pytest fixtures wired via runner conftest

AZ-410 (3pt) — FT-P-02 cumulative drift between satellite anchors:
- anchor_pair_detector.py: AC-1 detection, AC-2/3 pass-fraction,
  AC-4 monotonicity check, CSV evidence
- test_ft_p_02_derkachi_drift.py: scenario gated on upstream helper
  NotImplementedError (frame_source_replay / fdr_reader / imu_replay)

AZ-411 (2pt) — FT-P-03 + FT-P-14 schema + WGS84:
- estimate_schema.py: AC-1 schema completeness, AC-2 source-label set
  containment, AC-3 WGS84 range + int32 1e-7 decode
- test_ft_p_03_14_schema_wgs84.py: shared single-image-push scenario

Tests: 248 unit tests pass (+91 vs batch 68).
Reports: batch_69_report.md, batch_69_review.md (PASS),
cumulative_review_batches_67-69_cycle1_report.md (PASS).
