Feature: Full notification read view with conditional mark-as-read logic

- Added dedicated route and view for reading individual notifications (/account/notifications/read)
- Ensured notification is only marked as read if it hasn't already been
- Updated Notification model to use Subject and Body fields
- Fixed field references in templates (Title → Subject, Message → Body)
- Updated topbar dropdown to use correct field names and display logic
- Gracefully handle "notification not found" cases in template output
- Ensured consistent template parsing with layout and topbar inclusion
- Improved error logging for better diagnosis
