Adds custom incident forms

[whitdog47]

This pull request introduces custom forms for each incident, which can be created using a custom schema in the project settings. Multiple forms can be complete per incident and each have an optional attorney review and escalation screen.

Key Changes:
Form Creation via Custom Schema: The custom forms are created using a custom schema defined in the project settings. With the ability to create conditional questions, this feature provides flexibility and control over the form structure and questions, enabling users to capture the most relevant information about each incident for their unique use cases.

Custom Incident Forms via New Forms Tab in Incident Tab: Each incident now includes a 'Forms' tab. Incident commanders can create and fill out a form directly from this tab, streamlining the additional reporting requirements.

Forms Menu Item: All forms are now accessible and filterable through a new 'Forms' menu item. This central repository of forms enhances navigation and allows for efficient management and review of incident forms.

Read-Only Attorney Form: A specialized read-only attorney form has been added. This form enables attorneys to review the incident, make notes, and mark the form with status updates or escalation requirements.
