refactor(document): remove statusLabel() alias, use formatDocumentStatus directly

statusLabel() was a one-line alias for formatDocumentStatus() with no
additional behaviour. Remove it and update DocumentStatusChip.svelte to
call formatDocumentStatus() directly. Remove the corresponding alias
test suite from the spec file.
