Create appointment modal UX and UI updates

[zoe-gonzales]

Suggestions:

• Increase the height and width of the participants textbox; currently not easy to scroll through
• Filter the list of possible participants based on the appointment type (Which user types can participate in a consultation? A clinical? etc.)
• Update recurring meeting input labels to clarify what the inputs will do. Suggestion:

  
  Repeat <num occurrences input> times every <Repeat for num input> <Frequency select>

- Add a limit to future appointment times, or at least a warning message (was able to create an appointment in 2040)
