Updated the search pages

These pages now have a go back button, and improved flow and interaction
between edit and delete button phases.
added employeeVacc last minute

I figured it would be a good idea to include this page, after the
vaccinations have been confirmed/checked the page should no longer
display the dialog stating there are unconfirmed vaccinations. Just as
safety incase someone asks about it.
Changed the flow + more

The flow has been improved, the generate invoice buttons have been added
with dummy onclicks() that i'll fill out later. Also updated some
formatting and changed the button names from update vaccination to
confirm vaccinations.
Minor linking changes for improved flow
