Firebase update to version 9.x.x

[bidsinga]

EDIT
I accidently enforced App Check to our storage and realtime database, causing the app not loading any data.

Firebase got upgraded to v9. We need to update the config file and some Vue files that import firebase directly. Here is some documentation.

• Upgrade
• Compare v8 with v9

Any help with solving this issue is welcome and can be done in branch firebase-upgrade
