Add two-phase position estimation for roller shutters with blade tilt

Browse source 
Introduces descendTime and upSlatTime to model the two motion phases:
- Descent (slats unrolling) followed by blade tilt to fully close
- Blade opening followed by ascent when raising

Both fields are user-measured timestamps from the movement start,
making them easy to determine with a stopwatch. alphaDown and alphaUp
are now computed against the pure descent/ascent duration only,
excluding the linear blade-tilt phase at each end.
