[AZ-AUTODEV] Step 7 (Run Tests): smoke profile + green run

Add a fast integration profile so Step 7 (and future autodev
re-entries) can verify the full stack in ~2 min instead of ~15 min,
without losing access to the long-running coverage when needed.

- TestRunMode.cs: smoke flag + tightened poll/timeout values.
- Program.cs: env var INTEGRATION_TESTS_MODE / --smoke|--full CLI
  switch; smoke runs Tile + 200m region + simple route + ZIP route +
  Security; full keeps the existing sequence.
- RegionTests / ExtendedRouteTests: read timeouts from TestRunMode
  instead of hardcoding 120/180/360.
- docker-compose.tests.yml: forwards INTEGRATION_TESTS_MODE to the
  integration-tests container (default 'full').
- scripts/run-tests.sh: adds --unit-only / --smoke / --full flags,
  loads .env automatically, fails fast if GOOGLE_MAPS_API_KEY is
  missing.

Step 7 result: all tests passed in 111.86 s wall-clock (35/35 unit +
5/5 smoke integration scenarios incl. SEC-01..04). Report saved to
_docs/03_implementation/test_run_step7.md.

State advanced to Step 8 (Refactor).
