🔨(python-env) migrate meet main app to UV

Migrate main meet app to use UV for dependancy management.
Also optimized the backend image build sequence for faster rebuilds
when dependencies don't change.
Also removed compiled django translations files are they are done in the build
process now.

Changes inspired by drive repo.
