refactor(di): migrate from setter to constructor injection for logService

- Remove SetLogService methods from user, post, comment, and admin post services
- Add logService as constructor parameter to all dependent services
- Centralize call-related and message error definitions in app_errors.go
- Add ConversationID field to WSEventResponse for improved message tracking
- Simplify wire provider functions by removing manual setter calls
