Use launcher background on unlock screen

• /e/ version: e-1.5-S-testing
• Device model(s): FP3 + Beryllium (+ all)
• Device rooted: no

Summary

The new unlock screen display needs some improvement.

Description

What is the current behavior?

The new S-testing has a new unlock screen.

• The unlock-screen now could almost be mixed up with a dialer. This is a degradation compared to previous versions. The unlock page should have the lock symbol (as it was featured by previous versions) or should be titled "unlock your device)
• It needs more contrast (#6188)

What is the improved behavior?

If feasible (cf. this comment) use the Launcher's background on unlock screen.

If not, increase the contrast between the touchpad and the background like in this mock-up.

What does it bring?

Nicer and easier to use UI
