Add a option to create a patient from the prescription window

Don't implement new patient search ui.
Just add a new patient button to the bottom of the existing patient search ui.
Re-using existing patient search ui will allow us to re-use the existing patient search functionality.

Note

We have mockups for nice UI for this feature, for this issue lets see how much we can implement with the existing UI.
If time allows come back to the improved UI & workflow...
If re-using existing is going to create a lot work of, then lets discuss and decide on the best approach.

Acceptance Criteria 🧾

• Can see a create patient button when searching for a patient
• Clicking the create patient button will open the existing create patient form
• After saving the patient, will you'll be redirected back to the prescription window with the patient selected
