v0.1.1-alpha.9

• Query LLM costs from DB, so that no costs are hard-coded anymore
• Write tool use blocks into outputs too, because previously they were not instrumented and/or only stored as attributes
• Store provider keys encrypted in the DB, so we can run online evals with them
• Sheet view for text fields in the spans/traces view
• Small improvements around the onboarding and self-hosting experience
