FIX: force relative paths in coverage.xml

ISSUE: coverage.xml still contains absolute paths despite relative_files=True
ROOT CAUSE: pytest --cov=../ overrides .coveragerc relative_files setting
SOLUTION: explicit sed commands to convert absolute to relative paths

This is the final fix based on evidence from logs showing:
- filename="/home/runner/work/fmcrypto/fmcrypto/common/__init__.py"
- needs to become: filename="common/__init__.py"

Added verification step to confirm path fix works.
This MUST resolve the SonarCloud coverage detection issue.
