fix: restore schedule controls after failed saves (#148242)

* fix(ui): restore segmented controls after failed saves

Reconcile the actual disabled attributes after form-associated controls inherit a busy fieldset. Preserve explicitly disabled options and groups, and cover rejected automation saves through Chromium.

* test(ui): keep segmented controls disabled across busy renders

* test(wizard): route real config writes through database workers

Recovery and provenance integration cases use the host-owned SQLite broker. Keep them in the existing isolated forked lane so real config writes reach their intended ownership assertions. Production admission and test assertions remain unchanged.
