Address PR #1221 review round 3 feedback

- InspectorView: simulate the connect flow through "connecting" with a
  randomized 50-500ms handshake delay and an 85% success rate. On success,
  measure observed latency from connect start; on failure, set a plausible
  error message. Connection error message flows through to the active
  ServerCard's connection state. Real wiring (Phase 3) replaces this with
  `useConnection`.
- InspectorView: document that the view owns connection state (input
  `serversInput` connection fields are intentionally ignored), and mark
  `noop` callbacks as Phase-3 stubs.
- ServerStatusIndicator: add `showLabel?: boolean` escape hatch so consumers
  in constrained containers can override the default viewport-based
  visibility.
- ServerListScreen.stories: add `WithActiveServer` story exercising the
  dimming + `inert` behaviour in isolation.
- ViewHeader.stories: rename "Logging" → "Logs" to match `ALL_TABS` in
  InspectorView.
