fix(e2e): update selectors for redesigned UI (9 spec files)

- BTerminal → Agent Orchestrator (title, describe blocks, LLM context)
- Settings: .sidebar-panel → .settings-panel .settings-content,
  .dropdown-trigger → .dropdown-btn, .dropdown-option → .dropdown-item
- Settings open: [data-testid=settings-btn] + .panel-close
- Font controls: .size-control → .stepper, .size-btn → stepper button
- Terminal: data-testid selectors for toggle/tab-add
- Agent pane: .cost-bar → .status-strip/.done-bar, context meter conditional
- Project header: .cwd → .info-cwd
- Health: .health-dot → .status-dot
- Multi-project: proper this.skip() when single-project fixture
