TECHFORCE-49: remove unused elements and add unit conversion

• remove or hide current ramp settings: In details view, the setting was hidden instead of removed in case we need it for a different module that uses this feature. An option to add/hide this is not added, because we don't need this at the moment and don't know if this will be needed.
• remove emergency option in channel list, as this was not needed
• fix typos or swapped help texts
