[AZ-845][AZ-846][AZ-847] Refactor 02: relocate RouteSpec + widen lint

Cycle-3 refactor run 02-az507 (RouteSpec relocation + module-layout
refresh + AZ-270 lint widening). Single batch of 3 tasks; epic AZ-844.

AZ-845 — Relocate RouteSpec DTO to _types/route.py (rule-9 fix):
  * New canonical home: src/gps_denied_onboard/_types/route.py
    (frozen+slots dataclass; full docstring carried over verbatim).
  * c11_tile_manager/route_client.py imports from _types.route.
  * replay_input/tlog_route.py and replay_input/__init__.py keep
    re-exports for backward-compat (RouteSpec in __all__).
  * 5 test files updated to import from _types.route for symmetry.
  * Identity-preserving re-export verified by new test
    test_az845_routespec_canonical_home_and_reexport_identity.

AZ-846 — Refresh module-layout.md cycle-3 entries:
  * c11_tile_manager Internal list rewritten with all 8 internals
    (alphabetised) — corrects a stale entry that referenced files
    (satellite_provider_*.py) that no longer exist.
  * shared/replay_input file list adds errors.py (cycle-2 carry),
    tlog_ground_truth.py (cycle-2 carry), tlog_route.py (cycle-3 NEW).
  * shared/_types section registers route.py with provenance line.
  * Out-of-scope cycle-2 carry-overs (replay_api/, cli/render_map.py,
    helpers/gps_compare.py, etc.) intentionally untouched.

AZ-847 — Widen test_az270 lint to enforce full rule-9 allow-list:
  * test_ac6_only_compose_root_imports_concrete_strategies now walks
    every components/<X>/*.py ImportFrom/Import and rejects anything
    not in the rule-9 allow-list (own subpackage + _types + helpers
    + config/logging/fdr_client/clock + frame_source interface-only).
  * Strict superset of the original AC-6 narrow check.
  * Reports zero violations on the codebase post-AZ-845.
  * Two principled carve-outs documented in the test docstring:
    - components/<X>/bench/** path skip (measurement code legitimately
      constructs production strategies via runtime_root factories).
    - register_* lazy self-registration imports from
      runtime_root.<X>_factory (central-registry plugin pattern).
  * Both carve-outs surfaced to user via Choose A/B/C/D Risk-1
    protocol; user skipped both — agent proceeded with documented
    defaults. Doc-only follow-up tracked in
    _docs/_process_leftovers/2026-05-24_az847_rule9_wording_followup.md
    for rule-9 wording update in module-layout.md.

Test results: 2287 passed, 90 skipped (environmental — Docker / CUDA
/ TensorRT / Jetson hardware / fixtures), 0 failed. Focused subset
(replay_input/ + c11_tile_manager/ + test_az270_compose_root.py)
also clean: 169 passed, 1 skipped.

Tracker: AZ-845/846/847 transitioned In Progress -> In Testing.
