🚑️ Revert traefik v3

[mrnicegyu11]

What do these changes do?

Reverting the update to traefik v3 since there are more issues that remained undiscovered, and we have maneuvered the team into a position where an urgent release all the way from master to prod is necessary. No time to adress the remaining bugs for the moment.
