Remove call to generate demo data in tilt stack as it was never useful
to developers and only complicated the migration job unnecessarily.
Migration job should be laser focused on applying database migrations
rather than seeding mock data, improving clarity and reducing
complexity.
Replace mock Django secret key with longer version to resolve security
warnings in development stack.
Still not production-suitable as key remains versioned in repository,
but eliminates security warnings during development workflow.
Remove dependencies on bitnami Helm charts since recent changes in
bitnami organization led to charts no longer being maintained or
published.
Enhanced the Tilt dependencies to avoid any bootstrap or refresh
errors while developping using the Tilt stack.
Making components dependant from each others increase slightly
the time required to spin up the stack the first time.
