refactor(agent): keep the assistant in the nav, FAB and underlag flow only (#1557)

The founder wants the scattered per-page assistant buttons gone: the
assistant is reachable from the nav and the floating tab everywhere, so
in-page duplicates were noise. Removed the AgentSparkleButton call sites
(year-end, verifikat detail, supplier invoice detail, invoice editor)
and the now-orphaned component, the soft hand-off link in the Ny
verifikat modal (plus its i18n keys), and the transaction-row overflow
item. Kept: nav entry, floating tab, the Dokumentinkorg flow, and the
sanctioned "Skapa med assistent" split-button mode on /bookkeeping
(design.md convention 14).

The command palette's hand-off entries hardcoded the agent name "Anna";
they now use the identity from AgentSheetProvider like every other
affordance, and hide until agent onboarding is done (same gate as the
FAB).
