Refactor and update various components of EchoHub.Server

- Updated launchSettings.json for consistency. - Refactored FileValidationHelper to improve image validation logic. - Enhanced ServerDirectoryService for better connection handling and user count updates. - Improved DatabaseSetup for legacy database handling and seeding default channels. - Refined FirstRunSetup to ensure JWT secret generation. - Removed appsettings.Development.json as it is no longer needed. - Updated EchoHub.Tests project file for consistency. - Added unit tests for FileValidationHelper and PresenceTracker with improved assertions. - Updated ValidationConstantsTests to ensure regex validations are correct. - Cleaned up solution file formatting for better readability.
