[WIP] misc improvements to local dev

[johnclary]

Associated issues

• Use new street_levels column and drop old columns from db atd-data-tech#26248
• [DevOps] Misc updates to improve local devx atd-data-tech#26250

Two local dev changes here:

• You can now use the --apply flag with any vision-zero command that starts the graphql engine.
• The DB is now persisted locally, even when you stop and prune the compose stack. This solves a key pain point when you want to tweak env vars without fully replicating again.

Testing

1. Activate your VZ python environment and install requests if it's not already installed.

pip install requests

2. Start your local stack by replicating with the new --apply command ✨

 ./vision-zero replicate-db --apply

3. Query the DB to verify locations.street_level no longer exists:

select street_level from locations;
# ERROR:  column "street_level" does not exist

4. Now we will test that your db data is persisted locally. First bring down the entire local stack

./vision-zero local-stack-down

5. Now prune the containers and verify you do not have any docker remnants of the VZ stack

# prune the containers
docker container prune -f
# verify you have no running or stopped vision_zero containers
docker ps -a

6. Start the stack without replicating:

./vision-zero local-stack-up

7. The stack should start right up and there should be nothing to apply on the database. From the /database directory, verify the DB state matches what you expect:

hasura migrate status

8. Nice, your DB is now persisted!

9. Finally, start the VZE and head to the location details page to verify updated street levels column looks good. E.g. http://localhost:3002/editor/locations/153D618A97.

i considered trying to mirror the hasura CLI more closely such that we could use apply instead of --apply, but it would take some light refactoring of the parser setup to use suparsers. maybe i should go ahead and do that now?

./vision-zero local-stack-up apply

Revoking my review request until I have a chance to update our documentation as well
