progress_percentage lacked the active-state gate already applied to
progress/cycle_active/finish_time, so it kept showing a stale device value
(e.g. 1%) while idle -- now zeroed the same way. Shared by dryer/dishwasher/
oven via operational.py's OPERATIONAL_STATE.
Also exposes detergent/softener auto-dispense quantity, water hardness/
concentration, and low-reservoir alarms from /course/vs/0's options array,
using the same decode/RMW helpers already used for course selection and
drum-clean tracking. Gated by exists_fn so washer models without these
fields (e.g. the existing test fixture) are unaffected.
Water consumption is unaffected -- common.WATER_METER is already wired
into the washer registry; this reporter's device just doesn't expose
/water/consumption/vs/0.
