feat(test): Refactor z-w-s-b-test.sh to support more apps and loop

A loop feature was added to run endurance tests,
It was tested for 24+h along the next commit for sensor
and an issue has been observed, it will need deeper investigation,
check related tickets.

Only one app per type is supported, it may be improved later if needed
