Subject: auth: turn-time resolution in the TUI (inline login + 401 retry)

Resolve the active provider's auth before each turn via the AuthManager,
rendering an inline device-code prompt when login is needed, and force a
single refresh/exchange retry on a provider auth failure. Wire the manager
through RunOptions from main.zig.
