feat: show third-party licenses in About and generate aggregated license file #2

	name: licenses-drift-guard

	# THIRD_PARTY_LICENSES.md is generated from the resolved dependencies
	# (tool/generate_licenses.dart). This fails the PR if it drifts out of sync,
	# i.e. dependencies changed but the file was not regenerated and committed.
