refactor(ui): simplify navigation and session entry

[luokerenx4]

Summary

• Flatten the activity navigation and present Chat, Auto Quant and Auto Prediction as work areas with bounded recent Sessions and hover/focus actions.
• Add an independent Quick Start route that reuses existing Harness launch/setup flows, keeps separate drafts, and avoids conflicting Chat selection.
• Move Connectors into the Your Alice utility menu, relocate the portrait there, and simplify empty-workspace and Studio entry affordances.
• Enter paused Sessions by clicking the navigation row, with restore progress, duplicate-click protection and retryable errors. Keep process management in the options menu.
• Fix paused-session card overflow and remove the obsolete terminal card/canvas mode so the terminal fills the space below the shared top bar.

Verification

• pnpm test:owner:ui: 288 files, 1753 tests passed on the final UI implementation.
• cd ui && npx tsc -b: passed.
• git diff --check: passed.
• Real browser acceptance across navigation, utility menu, Quick Start/Chat selection, Harness switching and draft retention, uninitialized Prediction, and narrow viewport layout.
• Isolated runtime acceptance: created a test Session, stopped it, clicked its sidebar name, and confirmed automatic restoration to a connected native TUI. The CLI's model request returned 429, so this is terminal-lifecycle evidence, not successful model-response evidence.
• Real Grok terminal geometry: terminal body now fills the shell (680/680 px, then 860/860 px after resize); checked the existing connected user page without taking over its terminal.

Boundaries and residual risk

• UI and UI-owner documentation only; no backend APIs, credentials, trading execution, persisted Session shapes or process retention policy changed.
• Existing Session deep links and history-browser view-only behavior remain intact.
• Packaged Electron/app-mode acceptance was not run for this iteration; desktop-specific behavior remains unverified before release promotion.
• Previous integration PR refactor(ui): consolidate workspace and automation navigation #1378 and its post-merge dev run were successful. This PR targets dev, not master, and does not publish a release.
