feat: add polished boot screen on CLI startup (#118)

* feat: add polished boot screen on CLI startup

Replace the minimal one-liner REPL banner with an ANSI-styled status
panel that summarizes the agent's runtime state after initialization:
model, database, tool count, enabled features, active channels, and
the gateway URL. The boot screen is shown only in interactive CLI mode
(skipped for single-message -m mode).

* fix: address PR review feedback on boot screen

- Stop logging gateway auth token in tracing::info! (security)
- Use info.agent_name instead of hardcoded "IronClaw" in header
- Display embeddings provider in features line: "embeddings (openai)"
- Add Display impl for DatabaseBackend, simplify main.rs match
