Fix Windows test failures: filename compatibility and missing test data

[Copilot]

Windows CI tests were failing at Git checkout due to invalid filenames containing colons. Additionally, tests referenced non-existent data directories and used an undefined environment variable for venv activation.

Changes

• Filename compatibility: Renamed 14 CSV test files replacing : with - in timestamps

  • Windows filesystems reject colons in paths
  • Changed format: 2022-12-23 16:00:00 → 2022-12-23 16-00-00
  • Affected files in tests/resources/data/ and tests/resources/market_data_sources_for_testing/

• Test matrix: Added windows-latest to OS matrix in .github/workflows/test.yml

• venv activation: Fixed platform-specific paths

  if [ "$RUNNER_OS" == "Windows" ]; then
    source .venv/Scripts/activate
  else
    source .venv/bin/activate
  fi

  Previously used undefined $VENV variable

• Test data: Created tests/resources/backtest_reports_for_testing/

  • Added checkpoints.json with 16 algorithm IDs across 2 date ranges
  • Created 16 algorithm directories with algorithm_id.json files
  • Required by TestGetCheckpoints test suite

The filename issue was the primary blocker preventing repository checkout on Windows runners.

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:
