Use generic names for shared start/stop/pause entities

The /operational/state/vs/0 href (and its start/pause/stop buttons and
"cycle active" sensor) is shared across the dryer/dishwasher/oven/washer
families, but the entity names hardcoded laundry vocabulary ("Start
cycle", "Cycle active") that doesn't fit an oven's bake/roast session.
Rename to generic "Start"/"Pause"/"Stop"/"Running".

Also fold oven.py's duplicate stop button into a single STOP_BUTTON
constant in operational.py -- both wrote the identical state='Ready'
RMW, so there was no reason for two copies to maintain.
