fix: allow quoted identifiers in CREATE MODULE statement

CREATE MODULE "QuotedName" was a parse error because the grammar used
bare IDENTIFIER instead of identifierOrKeyword, unlike every other CREATE
command (ODATA CLIENT, ENTITY, MICROFLOW, etc.) which all accept quoted
names. DROP MODULE already used qualifiedName so the asymmetry also broke
round-trips involving reserved-word module names.
