fix(cli): add missing Type field, Config, Capabilities, and Tools panels to actor add rich output

Extended `_print_actor()` to render the full spec-required output for
`agents actor add`: the Actor Added panel now includes a Type field, and
three additional panels (Config, Capabilities, Tools) plus a success
status line are rendered when `show_add_panels=True`.

- Add `Type:` field to the Actor Added panel (from `config_blob["type"]`)
- Implement Config panel: Path, Hash, Options count, Nodes count, Edges count
- Implement Capabilities panel: bulleted list (rendered only when non-empty)
- Implement Tools panel: Rich table with Tool, Read-Only, Safe columns
  (rendered only when non-empty; string tool entries default to yes/yes)
- Add `✓ OK Actor added` success status line after all panels
- Pass `config_path` and `show_add_panels=True` from `add()` command
- Add Behave BDD scenarios covering each new panel and the success line
- Add Robot Framework integration test verifying the full rich output
