Fix iOS signing: add CODE_SIGN_IDENTITY and PROVISIONING_PROFILE_SPECIFIER to project.yml

The issue was that these settings need to be target-specific in project.yml,
not passed globally via xcodebuild args (which would conflict with SPM dependencies).

Successfully tested locally - archive builds and signs correctly.
