The editor content was only restored on reload in protected mode, and
stored_text was only synced on keystroke (oninput). So in the default
pause mode edited text came back empty after refresh/reload-workflow,
and upstream text passed without a keystroke was never captured.
Now applyPersistedMode restores the editor from stored_text in BOTH
modes, and syncStored also fires when upstream text arrives (socket)
and on Pass — so whatever text is shown/edited survives a reload.
Verified against the shipped litegraph serialize()/configure() widget
semantics: default-mode + pass-without-typing round-trips now restore.
