Creating new tables (Manager creation instead of selection)

[Gabetn]

Currently manager selects table# for device from dropdown, but it is limited by the DatabaseLoader file. It is unclear from our user stories if it is necessary for us to allow the manager to create a new table in that list.

This is low-priority as it is a simple task. We need to decide on what to do.

Do we even need a drop-down menu? Why not just make a text input, where the manager just types in a number.

[Gabetn]

Well, doing it via text input would require:

1. validation of input (make sure it's not already assigned).
2. creation of dining sessions inside the db in the case it's a new number

Whereas doing it via drop-down:

1. no need for validation since we can just display only the unassigned (which I already did)
2. creation of dining sessions is the thing I was unsure about us needing to do
