refactor: switch to custom DA client interface (#11)

* refactor: switch to custom DA client interface

- <daName>.go -> client.go for consistency

* chore: add docker-compose and smol tweaks

* refactor: remove 'da' suffix and rename to `client.go`

* forge install: blobstream-contracts

v4.1.0

* refactor: DABuilder -> ClientBuilder
