[BUG] Large alert_source_content will result in slow interface

[FideliusFalcon]

Describe the bug
If an alert contains a large number of fields in the "alert_source_content" it can significantly slow down the interface loading time. To address this, "alert_source_content" should only be returned when the frontend specifically requests it, such as when the "Toggle Raw Alert" option is activated.

To Reproduce
Steps to reproduce the behavior:

1. Create an alert with a large "alert_source_content" (+600 fields)
2. Request interface
