feat(shell): первый Slint-кадр на SDK (срезы C03/04/05/07/02) + slint GPL exception

theme::resolve_night (TDD); slint! AppWindow (статус-бар часы+сеть + грид тайлов + тема день/ночь);
main — best-effort чтение Settings/Power через sdk (без шины — дефолты, #4); часы UTC (локаль tz — позже).
deny.toml: GPL-3.0 exceptions для slint-крейтов (вариант A, финал к v4) + BSL-1.0 (error-code).
Slint тянет zbus5/thiserror2 — дубли версий (bans=warn). Реальный screenshot кадра — План 5 E2E.
