[AZ-315] Sync architecture docs after coupling refactor

Phase C of architecture coupling refactor (epic AZ-309). Closes the
last baseline finding (F5 — DataAccess incorrectly documented as
importing Common) and synchronizes the rest of _docs/02_document/
with the post-split project layout from AZ-312/313/314:

- module-layout.md: per-component sections for the three new csprojs
  with explicit ProjectReferences and the no-cross-sibling-reference
  invariant the split enforces.
- architecture.md: components and internal-communication tables
  updated to show calls flow through Common interfaces.
- architecture_compliance_baseline.md: F1..F5 marked Resolved with
  task IDs and commit refs; baseline summary now 0 findings.
- diagrams/components.md, components/03_tile_downloader/description.md,
  modules/{common_interfaces,services_tile_service,
  services_google_maps_downloader,tests_unit}.md updated for the
  split, RateLimitException relocation, and new ITileService methods.

Documentation-only batch — no code, no tests, no build changes.
Epic AZ-309 complete (6 tasks across 3 batches).

+# Batch Report
+
+**Batch**: 6 (refactor 02-coupling-refactoring · Phase C — final)
+**Tasks**: AZ-315

+
+## Task Results
+
+| Task | Status | Files Modified | Tests | AC Coverage | Issues |
+|------|--------|---------------|-------|-------------|--------|
+| AZ-315 Documentation sync | Done | 9 docs + dependencies table | n/a (docs-only) | 4/4 ACs | None |
+

+
+## AC Test Coverage
+
+4 of 4 ACs verified by inspection:
+- AC-1 (architecture.md reflects split) — verified
+- AC-2 (module-layout.md accurate) — verified
+- AC-3 (compliance baseline closed for F3/F4) — verified, also closed F5
+- AC-4 (no stale current-state references) — verified by grep; remaining matches are historical context
+
+## Code Review Verdict
+
+**PASS** — no findings. See `_docs/03_implementation/reviews/batch_06_review.md`.
+
+## Auto-Fix Attempts
+
+0
+
+## Build / Tests
+
+N/A — documentation-only batch. No code changes; no build needed.
+
+## Architecture-Baseline Impact
+
+- F5 (Low — DataAccess documented as importing Common): **resolved** (module-layout.md updated).
+- All five baseline findings (F1–F5) are now closed. Architecture compliance baseline shows 0 findings post AZ-309.
+
+## Epic AZ-309 — Closing Notes
+
+Epic AZ-309 (architecture coupling refactor) is complete with 6 tasks shipped across 3 batches:
+
+| Batch | Phase | Tasks | Outcome |
+|-------|-------|-------|---------|
+| 4 | A — endpoint routing | AZ-310, AZ-311 | Both tile endpoints now route through `ITileService`. F3 resolved. |
+| 5 | B — project split | AZ-312, AZ-313, AZ-314 | `SatelliteProvider.Services` split into three per-component csprojs with compiler-enforced sibling boundary. F4 resolved. |
+| 6 | C — docs | AZ-315 | All architecture docs synced. F5 resolved. |
+
+Aggregate verification:
+- `dotnet build SatelliteProvider.sln` — 0 warn, 0 err
+- `dotnet test SatelliteProvider.Tests` — 40/40 pass (35 baseline + 5 new from AZ-310/AZ-311)
+- `./scripts/run-tests.sh --smoke` — full integration suite green end-to-end
+
+## Next Step (Autodev)
+
+Refactor 02-coupling-refactoring complete. Return control to autodev orchestrator (Step 8 sub-step `verification` then `documentation`, then exit Refactor and proceed to Step 9).
