satisfactory: dev and server fall back instead of aborting (7.0.1)

--set dev=null aborted the render at .Values.dev.debug and --set server=null
at .Values.server.replicas, while the third block, game, has fallen back to
the chart defaults since 7.0.0. Half-safe is the worse state of the two:
whoever sees game=null work assumes server=null does too.

Both blocks now run through satisfactory.defaultedDict like game, via two new
helpers next to it. server.resources is deliberately NOT re-defaulted there -
it already runs through satisfactory.effectiveResources, which carries those
defaults and is null-safe on its own, and a second copy of limitFactor: 2 /
4Gi / 1 / 5Gi would be a third place for them to drift.

server is read in four files, not one, and the fourth is NOTES.txt, which
helm template never renders - a fix confined to the manifests would have
looked green and still aborted on a real helm install. All four go through
the helpers.

The single erased key was the quieter half of the bug and is fixed with it:
a nulled server.gamePort rendered "port:" and "nodePort:" empty into the
Service and an empty containerPort into the StatefulSet, and a nulled
server.storage a PVC asking for no size - manifests rejected by nothing until
the API server saw them. server.storage was documented in values.schema.json
as deliberately not null-safe; that reasoning does not survive the block-level
case, because it made "server: null" render a sizeless PVC instead of falling
back like everything else. The schema note is replaced rather than left lying.

Rendered output for valid values is unchanged: helm template against the
chart defaults and against a full override set is byte-identical to 7.0.0,
and so is NOTES.txt. Hence a patch bump, appVersion untouched.

Fixes #16
