improve form styling, sizing, and error messaging

[jbibla]

currently, including tooltips only when a button is disabled is not possible out of the box. the solution would be to either add a message for enabled buttons (which is redundant and would not be consistent with other buttons throughout the app) or duplicate buttons in the template to account for the various states (v-if for availableAtoms connected oldBondedAtoms etc...). my thinking has changed on this subject and i no longer thing that using tooltips for disabled buttons is the right thing to do.

since we have the new Connecting... value for buttons I think we should 1) leave all modal-triggering -buttons enabled and rely on proper form validation to communicate with the use and 2) disable form submission buttons unless a minimum amount of information is included (i think this is already the case).

i would like to close this ticket and open a new ticket to address proper form validation and error messages to continue the work @sabau completed in #1710.

this would mean that modal-triggering-buttons will only be disabled based on connected and form submit buttons would be enabled when a minimum amount of info is included. also, we need to display inline error messages on form elements and keep the modals open unless there is a successful submission.
