chore: add flags projectListImprovements and useProjectReadModel (#7905)

These are both related to the work on the project list improvements
project.

The `projectListImprovements` flag will be used to enable disable the
new project list improvements.

The `useProjectReadModel` flag will be used to enable/disable the use
of the new project read model and is mostly a safety feature.
