Make Button Title Dependent on the Medication Modification State (#6)

# Make Button Title Dependent on the Medication Modification State

## ♻️ Current situation & Problem
- Feedback we received from users of the Medication Module:
> Upon clicking medication settings, the only way a user can go back is
either by clicking "cancel" or swiping down from the upper third of the
screen. Propose changing "cancel" to "close." Important to leave
"cancel" when adding a new medication as in that situation you would be
cancelling the action.


## ⚙️ Release Notes 
- Show "close" instead of "cancel" in the case that a medication has not
yet been changed.
