Implement initial comId

[KallynGowdy]

This issue tracks the work on an initial implementation of comId. comId is a set of features which enable a studio to have its own branding and configuration. For now, the goal is to support more custom branding features and focus on providing organizations more options for managing teams and projects.

Backend Implementation Details

• [x] A studio can have a comId
• [x] A studio can have a parent studio (referenced by comId)
