refactor: abstract codecov submission script

- Use CODECOV_TOKEN environment variable instead of hardcoded token
- Automatically detect latest commit SHA from git
- Automatically detect latest PR number from GitHub API
- Support GITHUB_TOKEN for PR detection
- Support GITHUB_REPOSITORY and COVERAGE_FILE environment variables
- Add error handling and informative output
