Prepare self host mode

[djhi]

Problem

Fixes #89

We want to ease self hosting.

Solution

• Initialize supabase docker configuration on request to avoid replicating it in the repo which would require us to sync it too
• Document how to configure it properly
• Document how to apply migrations
• Configure the new publishable keys

How To Test

Follow the Self Hosting documentation added in this PR

Additional Checks

• The documentation is up to date

Also, please make sure to read the contributing guidelines.

I couldn't start everything without setting these params first:

FRONTEND_HTTP_HOST=true
FRONTEND_HTTP_PORT=3000
FRONTEND_HMR_PORT=3001

make docker-start output:

docker compose -p atomic-crm --env-file .env.development --env-file ./docker/.env -f ./docker/docker-compose.yml -f ./docker/docker-compose-atomic.yml up

Yes, that's explained in the self hosting documentation

🤦‍♂️ you are right

[WiXSL]

No mention of updating VITE_SUPABASE_ANON_KEY to the ANON_KEY from docker/.env.
With the demo key, signup returns 401 “Invalid authentication credentials,” blocking the first user.

Worth mentioning in the docs:

After editing .env / .env.development, you must restart the stack (make docker-stop + make docker-start) so containers pick up the new values.
