fix(security): add rstrip('/') to get_target_repo for trailing-slash URLs

The regex r'[:/]([^/]+/[^/]+?)(?:\.git)?$' fails on URLs with trailing slashes
like 'https://git.softuniq.eu/UniqueSoft/APAW/' because the final '/' breaks
the pattern. Added .rstrip('/') in Python and sed 's:/*' in Bash to all
get_target_repo() implementations across 11 files.
