Marc Billow 10ab51c7f3 fix(fridge,observe): merge partial cache updates, name ice makers dynamically
Issue #27: the flex-zone/cooler-drawer select vanished after a device
stopped including supportedOptions on an update for /mode/vs/0.
ObserveManager.apply() handed reps straight to StateCache.apply_rep,
which fully replaces the cached rep -- so a partial update (missing a
field the select's exists_fn/options_field gate on) silently erased
data a fuller update had previously supplied. apply() now merges
incoming reps onto whatever's already cached instead.

Also give ice-maker entities (and any future pattern-cap instance) a
device-given display name instead of the href-derived "Icemaker
One"/"Icemaker Two": Capability.name_field lets a pattern capability
read and normalize an instance name (e.g. iceMaker.name's "CUBED_ICE")
for use as the entity name prefix, independent of the stable
key/unique_id.
