…ap-java#162)

Add DEFAULT_MIN_VALUE/DEFAULT_MAX_VALUE (and DEFAULT_STEP for float
characteristics) and a constructor taking min/max (and step) to 19
characteristics that only supported fixed ranges, following the pattern
of RotationSpeedCharacteristic. Existing constructors delegate with the
previous values, so their serialized output is unchanged.

Percentage characteristics and hue have fixed ranges by definition, so
only the tilt angles keep the min/max constructors.

The Home app shows no control for the Slat service, so a custom range
cannot be verified there.

JmdnsHomekitAdvertiser created its own JmDNS when given an InetAddress but
never closed it, and registered a shutdown hook on every advertise() that was
never removed. Each stopped HomekitRoot therefore left a running JmDNS
instance behind, kept reachable by its shutdown hook.

stop() now removes the shutdown hook, closes the JmDNS only if the advertiser
created it, and resets the advertising state so later changes to
discoverability, MAC or configuration index do not re-register the service.

Add custom min/max to window covering tilt angle characteristics

Close owned mDNS instance and remove shutdown hook on stop
