feat(providers): simplify modal to use published base image

Browse source 
The `-full` base image already includes sandbox-agent and all agents
pre-installed. Remove redundant apt-get, install script, and
install-agent dockerfile commands from the Modal provider.

Also allow overriding the default image via SANDBOX_AGENT_IMAGE env var
across all providers for testing with different published versions.
