Patients Portal: the dosage units list does not any logical order

[dvribeira]

From L-Z's feedback:

Le menu déroulant QUantity est complétement mélangé (pas de logique ni de formes ni alphabetiques)

Work in progress by @ronaldo-loureiro as part of the enhancement of index data integration:

• The list will be shortened to index proposed dosage units, if any.
• The list will be presented in alphabetical order.
• If feasible, the possibility to start writing the name of an unit to filter the list will also be implemented.
