fix: prevent webhook deploy crash when commit data lacks modified files (#4470)

shouldDeploy passed undefined/null entries from commit.modified straight
into micromatch, which throws "Expected input to be a string" and fails
every webhook deployment when watch paths are configured. Filter out
non-string values before matching.
