Upgrade dependencies, add encrypted connection strings

- Updated NuGet packages across projects for compatibility and bug fixes
- Switched to Microsoft.OpenApi and refactored Swagger setup
- Added AES encryption/decryption for connection strings
- Stored encrypted DB/cache connection strings in config
- Improved encryption reliability in Program.cs
- Added AutoMapper to multiple projects for mapping support
- Enhanced security and code maintainability
