BE: Fix HTTP 500 on protobuf Any type

[DimaVilda]

issue link:
Fixes #650

• Breaking change? (if so, please describe the impact and migration path for existing application instances)

What changes did you make?

• Fixed serialization of Protobuf messages containing Any type fields
• Added TypeRegistry support in ProtobufFileSerde to properly handle Any type resolution
• Added test cases to verify handling of Any type messages

Is there anything you'd like reviewers to focus on?

• Implementation of TypeRegistry in the serializer method
• Integration test to check this case

How Has This Been Tested? (put an "x" (case-sensitive!) next to an item)

• No need to
• Manually (please, describe, if necessary) - bug was reproduced on self made project using steps from issue 650, checked error stack trace to see what is wrong
• Unit checks
• Integration checks
• Covered by existing automation

Checklist (put an "x" (case-sensitive!) next to all the items, otherwise the build will fail)

• I have performed a self-review of my own code
• I have commented my code, particularly in hard-to-understand areas
• I have made corresponding changes to the documentation (e.g. ENVIRONMENT VARIABLES)
• My changes generate no new warnings (e.g. Sonar is happy)
• I have added tests that prove my fix is effective or that my feature works
• New and existing unit tests pass locally with my changes
• Any dependent changes have been merged

hey team
one more thing to notice!
ProtobufFileSerdeTest and MessagesServiceTest tests don't work on Windows environment. error is:
' ProtoFile not found for import 'language/language.proto''

Why?
Because in ProtoSchemaLoader you call

  Map<String, ProtoFile> filesByLocations = new HashMap<>();
  filesByLocations.putAll(knownTypes);
  filesByLocations.putAll(loadFilesWithLocations());

and the problem is in 'loadFilesWithLocations' and in

private Loader createFilesLoader(Map<String, ProtoFile> files) {
  return new Loader() {
    @Override
    public @NotNull ProtoFile load(@NotNull String path) {
      return Preconditions.checkNotNull(files.get(path), "ProtoFile not found for import '%s'", path);
    }

methods because in Windows paths use backslashes () but proto imports use forward slashes (/), so better would be create a ticket to normalize paths on both OS and be able to run project. I will create it and provide you a fix for it with a few additional test cases.
Feel free to ask me questions

@DimaVilda yeah aware of it, been discussed here: #261. If you can fix them without altering production code, I'd be happy to accept such changes.

@Haarolean , wdym without altering production code? There is incorrect backslashes processing in loadFilesWithLocations() so how can we fix it without touching it ? Or did I misunderstand your commet ?
