[UX] Inconsistent user experience between providers and tests from the same provider

The UX of using checkbox touch is different depending on which provider you are using.

When you are using manual tests, in the verification page you will get:

Small buttons at the bottom for Yes No. To skip the test you have a button in the header.

In the QML tests, the verification part of it is not part of a "real" verification, but coded directly in the test itself.

This makes the experience inconsistent

Camera test:

Two big "Pass" "Fail" (instead of Yes/NO) and a small "Restart" button.

Haptics:

A small button to activate the haptics, and three big buttons this time, one for Pass, one for Fail, one for Skip

Edges:

Two big (but smaller) buttons to "Start" or "Skip the test" (instead of just Skip) to start the test.
In the verification, three big buttons (but again, smaller), this time with the labels "Yes", "No" and "Skip the test"

Virtual Keyboard:
Same as edges

Long press:
"Press and Hold" and two small buttos "Skip the test" "Fail the test"

Battery discharge:
A small button to Skip

Now that we have a relative small amount of tests, we should define the UX and make it consistent throughout the application.
