feat(dashboard): wire medication-intake action into the Hinzufuegen menu

Add the third row to the dashboard quick-add DropdownMenu so a
medication-intake event can be logged without leaving the page. The new
ResponsiveSheet shares the same footer-portal contract as the existing
Measurement and Mood sheets so the Save and Cancel buttons sticky-pin
above the mobile soft keyboard, and the menu label is a self-contained
verb-phrase ('Medikamenteneinnahme erfassen' / 'Log medication intake')
that doesn't collide with the trigger or the sibling rows.
