Oleksandr Bezdieniezhnykh bb744d9078 [AZ-420] Batch 81: FT-P-12 + FT-P-13 GCS scenarios
FT-P-12: parse mavproxy-listener tlog over a 60 s Derkachi replay and
assert SUT->GCS GLOBAL_POSITION_INT cadence lands in [1, 2] Hz (AC-6.1).

FT-P-13: inject `RELOC:<lat>,<lon>,<radius_m>` STATUSTEXT while the SUT
is in dead_reckoned; verify FDR `c8.gcs.operator_command` ack <=2s,
`anchor_search_region` centre shifts toward the hint, and no
BAD_SIGNATURE / UNAUTHORIZED / REJECTED STATUSTEXT lands in the
post-inject window (AC-6.2).

Adds runner.helpers.gcs_telemetry_evaluator (rate, hint-ack correlation,
haversine search-region shift, rejection scan) and
sitl_observer.capture_gcs_tlog (parity surface to capture_ap_tlog).
Pure-logic coverage: 39 new unit tests; full e2e/_unit_tests/ suite
746 passing (was 700). Scenarios skip locally on missing SITL replay
fixture; production hooks (inbound STATUSTEXT parser, anchor_search_region
FDR emitter) tracked outside this task.

See _docs/03_implementation/batch_81_report.md +
reviews/batch_81_review.md.

"""FT-P-12 — GCS downsample at 1-2 Hz (AZ-420 / AC-6.1).
The full scenario:
1. Start the SUT against the SITL container; ``mavproxy-listener``
captures the SUT↔GCS link to ``${E2E_SITL_REPLAY_DIR}/gcs_tlog_<host>.tlog``.
2. Replay ``flight_derkachi.mp4`` for 60 s through the SUT's file frame
source so the C8 ``QgcTelemetryAdapter`` produces summary bursts.
3. After replay, parse the captured tlog for SUT-emitted
``GLOBAL_POSITION_INT`` (the position half of the QGC summary pair)
over the 60 s window.
4. AC-1: observed rate must land in [1, 2] Hz inclusive (AC-6.1).
5. AC-5: parameterised per ``(fc_adapter, vio_strategy)``.
Gated on:
* ``runner.helpers.frame_source_replay`` — owned by AZ-441 (still a
stub today; scenario skips via ``sitl_replay_ready``).
* ``runner.helpers.sitl_observer.capture_gcs_tlog`` — owned by AZ-420
(AP-side parity surface to ``capture_ap_tlog``; loads the
``gcs_tlog_<host>.tlog`` FDR-replay fixture).
* ``runner.helpers.gcs_telemetry_evaluator.compute_gcs_summary_rate`` —
pure-logic evaluator covered by
``e2e/_unit_tests/helpers/test_gcs_telemetry_evaluator.py``.
