• [x] deselect ALL when bulk window is opened (remove stored prefences again)
• [x] enable template processing for bulk mails (just name, which is the external preferred name)
• [x] when adding new dyntreat init state => immediately expand all "+" (only if not yet persisted) OR focus input for blood
• [x] add mail address column in gcal sync table
