UI: independant screens (move Toolbar... outside of Main Activity)

[mmathieum]

In order to:

• support predictive back gesture
• better support of edge-to-edge
• start migrating to Compose screen-by-screen
• ...
  toolbar needs to be moved to fragment

---

Try doing it gradually by adding a boolean to ABFragment to know if screen is managing its own toolbar or not.
