chore: clean up mise aws deploy tasks

[scottgerring]

This PR makes mise aws:deploy:local work properly for individual services, not just at a stickerlandia-wide level. It also adds dependencies between the individual services and infrastructure (everything depends on infra, everything other than user-service depends on service-service), so that the requirements are automatically pulled in.

I've done this by introducing a distinction between DEPLOY_MODE and COMMIT_SHA. We use the former to choose to toggle on "local deploy" or "prebuilt release images" mode; if it is unset, we deploy using images tagged with the COMMIT_SHA.

If you set COMMIT_SHA to some actual hash and run a cdk deploy directly, you can deploy a particular version to AWS using the tagged GHCR images.

	# aws: AWS deployment tasks
	#
	# Deployment modes are controlled via the DEPLOY_MODE environment variable:
	# - local: Build containers from local Dockerfiles (DEPLOY_MODE=local)
	# - release: Pull prebuilt images from GHCR tagged "latest" (DEPLOY_MODE=release)
	# - (unset): Falls back to COMMIT_SHA env var, or "latest" if not set
	#
	# DEPLOY_MODE is NOT stored in .env, so it propagates naturally through
	# subprocess calls. CDK's SharedProps reads DEPLOY_MODE and sets the
	# appropriate image tag. Services can define their own aws:deploy:local
	# and aws:deploy:release tasks that set DEPLOY_MODE and delegate to aws:deploy.
	#
	# To deploy a specific tagged version from the registry (e.g., a CI-built
	# image), set COMMIT_SHA to the desired tag and run aws:deploy directly
	# without setting DEPLOY_MODE. For example:
	# COMMIT_SHA=abc123 npx cdk deploy (from infra/aws directory)
