fix: edit ops second review findings

- A group's sunSensor and a shade's flags are refused by name: the routes
  don't set them.
- setPaired needs paired, and without a shade id it is a bad request.
- groupOptions' payload is parsed in ProtoEdits (parseReadPayload).
- The assembler's mutex is static, so creating it can't fail.
- protoIsReadOp and protoIsShadeOp are gone; the tests use protoOpKind.
- Native tests for missing(), offeredRemoteAddress and the edit ops
  against the TYPE table.
