Fix six GUI defects, verified live against the real stack:
- NavSessions: mark the in-progress (active) session in yellow (warning
token) — both its status dot and its row background.
- SteerInput: the composer is now an auto-growing textarea that wraps and
grows vertically (caps at 160px, then scrolls); Enter sends, Shift+Enter
inserts a newline.
- WorkflowBar: show a synthetic title of the current phase under the 8 dots
from static EN/IT strings (no LLM); English is displayed to match the chrome.
- CentralStatus: reformat the 5-line system-message tail as a structured,
monospace list with per-line markers and an emphasized last line.
- AppShell + CentralStatus: move the left Model-activity panel toggle off the
working spinner (now a pure status indicator) onto a dedicated arrow button
(→ opens, ← closes).
- gate: rename the phase-confirm button "Conferma e prosegui" → "Salva e
procedi" (builders.js + its L1 test).
