refactor(planner): a day head's pill row moves into a module of its own

The stays, hire cars and plugin label under a day's name now live in DayHeadPills, so DayPlanSidebar shrinks back under its size baseline. The stay fields are read through their types instead of an any cast, and the size, eslint and theme-disable baselines are lowered to the new counts.
