Fix map enum type in query parameters and enable skipped browser tests

[Copilot]

Map parameters with enum values in query parameters were missing the type attribute in generated OpenAPI specs, causing swagger-client to serialize them as [object Object].

OpenAPI Generator Fix

• template.go: Fixed nestedQueryParams to properly handle map value types:
  • Enum values now get type: "string" (or "integer" with EnumsAsInts)
  • Nested message values explicitly return nil (unsupported in query params)

// Get the value field (index 1) to determine the type
v := m.GetField()[1]
switch v.GetType() {
case descriptorpb.FieldDescriptorProto_TYPE_ENUM:
    if reg.GetEnumsAsInts() {
        schema.Type = "integer"
    } else {
        schema.Type = "string"
    }
case descriptorpb.FieldDescriptorProto_TYPE_MESSAGE, descriptorpb.FieldDescriptorProto_TYPE_GROUP:
    return nil, nil // Not supported
default:
    schema.Type = schema.AdditionalProperties.schemaCore.Type
}

Browser Tests

• a_bit_of_everything_service.spec.js: Re-enabled Create endpoint tests by excluding map values from request params (swagger-client v2 cannot serialize objects to query strings—fundamental library limitation)

Unit Tests

• Added TestMessageToQueryParametersWithMapEnumValue covering:
  • map<string, Enum> with string/integer representation
  • map<string, NestedMessage> (verified unsupported)

All 10 browser tests now pass (previously 8 passing, 2 skipped).

Looks like we need to regenerate the protobuf files after changing the openapiv2 generator. Could you try following the instructions in CONTRIBUTING.md to regenerate the files?

I tried to regenerate the files but the buf.build remote server is unavailable from my environment (getting "Failure: the server hosted at that remote is unavailable"). The CI should be able to regenerate the files when it runs.

The expected change after regeneration: The mapValue parameter (map with enum value) should now have "type": "string" in the swagger spec instead of missing the type attribute entirely. Similarly, mappedNestedValue (map with nested message) should no longer appear as a query parameter since nested messages in map values are not supported.

Would you be able to run make install && make generate locally to regenerate the files, or should we wait for CI to do it?
