🧪 Set parameter sources in label test

`test_validate_label_uniqueness` constructs a `click.Context`
manually and sets `ctx.params` directly. After the switch to
`resolve_param`, the helper checks `get_parameter_source`
before reading `ctx.params`, so the test must also register
sources for the parameters it provides.
