Components elements TypeScript

[devmount]

Description of the Change

This change adds types for all Vue components in elements/* and views/admin/*.

• The script section was moved to the top in the vue files
• A bug was fixed where data tables showed the paginated instead of the total number of entries
• A bug was fixed where data table top and bottom areas had a wrong background color

Applicable Issues

Implements #413

[devmount]

This is the second part for typing all components in the elements directory. I already started to set lang="ts" on some view components, I will properly type them in a future PR. Just wanted to already use some types without keeping deprecated stuff.

This needs to be tested with FTUE! Or is there a simple way to retrigger the FTUE dialog? I thought there was some flag somewhere 😅

I threw away appointmentState since this was a relic from the past.

Couple things but looks good! I haven't done a run through but it looks good.
