1. Various updates to the appointment booking page:
    - disabled the "Proceed to Booking" button if the patient's PHN was not found (i.e. they are a new patient)
    - changed the "No, search again" button that appears if the patient's PHN/DOB combination is invalid to "No, review my PHN"
    - added a "No, I have a new PHN" (i.e. they are an existing patient at the clinic but their PHN has changed) button that prompts the patient to contact the clinic to update their PHN
    - changed the date format in the datepicker from "2020-08-26 (Wednesday)" to "Wednesday, August 26th, 2020"
    - changed the "If you are experiencing a medical emergency, please do not book..." message from red "danger" to yellow "warning"
    - added email (mailto:) links to all error messages that say "please contact the clinic for assistance"
    - changed the expired referral error message (for rostered booking workflows, e.g. pediatrician) to add a link to book a walk-in appointment
    - added an error message for booking workflows that do not accept new patients that links to /drop-in
  2. Changed the queue numbers on the homepage to display "CLOSED" instead of "0".
  3. Updated the /drop-in page and the Staff Sign In page to use the new Cortico branding.
  4. Fixed bug in the "Oscar master file" dropdown button in the video appointment page (only applies to clinics with an internal Oscar IP and an external Oscar URL).
  5. Fixed bug in same-day booking rule "Patients can't book multiple appointments across family doctor or walk-in workflows" where some workflows (e.g. Specific Doctor Walk In) were being considered as specialist workflows instead of walk-in.
