[Table] - Enforce Null and Empty fields

[clun]

When reading data from tables, for empty request column enforce null or empty

• for collection
• for set
• for map
• for udt
• for any scalar

Object fallback = switch (type) {
                case LIST        -> new ArrayList<>();
                case SET         -> new LinkedHashSet<>();
                case MAP         -> new LinkedHashMap<>();
                case USERDEFINED -> buildNullUdt(entry.getValue().getDefinition());
                default -> null;
            };
            row.getColumnMap().put(columnName, fallback);

//....

    private Map<String, Object> buildNullUdt(TableUserDefinedTypeDefinition definition) {
        if (definition == null) return Collections.emptyMap();

        Map<String, Object> nullUdt = new HashMap<>();
        definition.getFields().keySet().forEach(field -> nullUdt.put(field, null));
        return nullUdt;
    }
