Refactor and update test projects, remove obsolete tests, and upgrade dependencies

- Deleted obsolete test files for SchedulerAuditService and SchedulerMongoSessionFactory.
- Removed unused TestDataFactory class.
- Updated project files for Mongo.Tests to remove references to deleted files.
- Upgraded BouncyCastle.Cryptography package to version 2.6.2 across multiple projects.
- Replaced Microsoft.Extensions.Http.Polly with Microsoft.Extensions.Http.Resilience in Zastava.Webhook project.
- Updated NetEscapades.Configuration.Yaml package to version 3.1.0 in Configuration library.
- Upgraded Pkcs11Interop package to version 5.1.2 in Cryptography libraries.
- Refactored Argon2idPasswordHasher to use BouncyCastle for hashing instead of Konscious.
- Updated JsonSchema.Net package to version 7.3.2 in Microservice project.
- Updated global.json to use .NET SDK version 10.0.101.
