Chores: remove team references

[inimaz]

Issue ==> https://github.com/orgs/mlco2/projects/4/views/1?pane=issue&itemId=67355803

Goal is to remove the team to avoid too many dependencies. New structure will be:

• Orga

  • Project
    • Experiment
      • Run
      • Measure

• User

TODO:

• [x] Remove references to the team
• [x] Alembic migration
• [x] How to do a /v2 of the API without affecting the current dashboard? This PR will delete all references to teams in the db ==> it will break the dashboard Not applicable. We will create new db from scratch when release is ready.

Seems like we can forget the current API version and dashboard and just go ahead and break it.

migration for another PR ?

ah @prmths128 since we said we would do a dump, I understood it was not needed and I removed it dfef868 🤦‍♂️ I can do another PR and add it later if that's ok?
