v3: self-hosting

[nicktrn]

This PR makes the necessary changes to allow for a simpler self-hosting setup using the docker provider.

Changes:

• Provider and coordinator images will be built and released just like the webapp, e.g. the usual tags and pushes to main
• Better checkpoint function test with remediation hints
• Checkpoint simulation can be controlled via a new optional env var: FORCE_CHECKPOINT_SIMULATION
• The init command displayed in the dashboard will include a custom api URL if needed
• A new optional env var to make users admins on account creation: ADMIN_EMAILS (regex)
• A new optional env var to disable telemetry across CLI and other components: TRIGGER_TELEMETRY_DISABLED
• Pin SDK during init command
• CLI command output will include custom api URL if needed
• Don't retry final checkpoint errors
