chore: Add justfile for common tasks

[tpoliaw]

Simplifies the various common tasks that should be run during
development.

Can be added to over time but for now mainly wraps running compose
services and calling blueapi so config files don't have to be specified
for every command.

This is a cool feat, could we also add an doc update to reference this ?

I imagine the tasks are going to need adjustments when they meet every day use so I'm tempted to leave it as an undocumented development thing for now and then write it up when they've settled down a bit.
