[AZ-289] [AZ-290] Batch 3 tests: integration ZIP cap, perf, security, queue

AZ-289 — RL-01 50MB ZIP cap added to RunRouteWithTilesZipTest;
existing integration tests already cover BT-08/BT-09 + AC-1/AC-2.

AZ-290:
- scripts/run-performance-tests.sh extended with PT-01/03/04/05
- SatelliteProvider.IntegrationTests/SecurityTests.cs (SEC-01..SEC-04),
  wired into Program.cs
- SatelliteProvider.Tests/RegionRequestQueueTests.cs covering RS-04 /
  RL-02 queue capacity behavior

Notes:
- RS-04 spec wording ("rejects overflow") drifts from the channel's
  BoundedChannelFullMode.Wait back-pressure semantics. Tests assert
  the actual behavior; spec to be reconciled in Step 12 (Test-Spec
  Sync). Tracked as Low/Spec-Gap in batch_03_review.md.
- Unit tests: 35/35 passed (Docker .NET 8 SDK).
- Integration test project builds clean (0 warnings, 0 errors).

+# Integration Tests: Route Map Processing + ZIP
+
+**Task**: AZ-289_integration_route_maps
+**Name**: Integration tests: route map processing + ZIP
+**Complexity**: 2 points
+**Dependencies**: AZ-285
+**Component**: Blackbox Tests
+**Tracker**: AZ-289
+**Epic**: AZ-284
+
+## Scenarios
+
+- BT-08: Route with requestMaps=true — verify mapsReady=true, stitchedImagePath, csvFilePath
+- BT-09: Route with createTilesZip=true — verify ZIP contents match CSV tile count, directory structure preserved
+
+## System Under Test Boundary
+
+Tests drive the API via HTTP endpoints. No internal module stubs — all services run in Docker as production.
+
+## Test Data
+
+Route points from test_coordinates.md (ROUTE-02, ROUTE-03)
+
+## Notes
+
+BT-10/11/12 are already covered by existing integration tests (ComplexRouteTests, ExtendedRouteTests).
+
+## Acceptance Criteria
+
+AC-1: Route map processing completes within 180s
+AC-2: ZIP file structure is validated (entry count matches CSV, path prefix "tiles/")

+# Non-Functional Tests
+
+**Task**: AZ-290_nonfunctional_tests
+**Name**: Non-functional tests: perf, resilience, security, limits
+**Complexity**: 3 points
+**Dependencies**: AZ-285
+**Component**: Blackbox Tests
+**Tracker**: AZ-290
+**Epic**: AZ-284
+
+## Performance Scenarios (PT-01 through PT-06)
+
+- PT-01: Tile download latency <30s
+- PT-02: Cached tile retrieval <500ms
+- PT-03/04: Region processing throughput
+- PT-05: 5 concurrent regions all complete
+- PT-06: Route interpolation <5s
+
+## Resilience Scenarios (RS-01 through RS-06)
+
+- RS-01: API starts with database ready
+- RS-02: Migrations run on fresh DB
+- RS-03: Region processing handles tile failures
+- RS-04: Queue rejects overflow (capacity 1000)
+- RS-05: Max 4 concurrent downloads
+- RS-06: Route processing completes all regions
+
+## Security Scenarios (SEC-01 through SEC-04)
+
+- SEC-01: SQL injection via coordinates
+- SEC-02: Path traversal in tile serving
+- SEC-03: Oversized region request
+- SEC-04: Malformed JSON
+
+## Resource Limit Scenarios (RL-01 through RL-04)
+
+- RL-01: ZIP ≤ 50MB
+- RL-02: Queue capacity 1000
+- RL-03: Concurrent download semaphore (4)
+- RL-04: Concurrent region processing (20)
+
+## System Under Test Boundary
+
+All tests drive the system via HTTP API or observe Docker container behavior.
+
+## Acceptance Criteria
+
+AC-1: Performance scripts (scripts/run-performance-tests.sh) pass thresholds
+AC-2: Resilience tests verify state transitions and resource limits
+AC-3: Security tests confirm no injection or traversal vulnerabilities
