feat(cli): redesign dashboard for ATmosphereConf demo (#140)

* feat(cli): redesign dashboard for ATmosphereConf demo

Two-column layout (Repository | Network) instead of three columns for
narrow terminals and split-screen use. Key changes:

- Account status (ACTIVE/INACTIVE) displayed prominently in header
- Identity checks (handle resolution, DID document) in Network panel
- Per-relay host status (active/idle/offline) replaces commit sync check
- Separated activation beats: [a] activates only, [r] and [e] are
  independent steps with contextual keybinding visibility
- Firehose commit events trigger debounced repo refetch for faster UI

* Change ascii art
