Add Sunnylink registration check and process

The commit introduces a new function, sunnylink_need_register, to check if the Sunnylink feature is registered. It also updates the process list to always include the manage_sunnylinkd process and introduces a new process for Sunnylink registration if it's enabled but not registered.
