dot kde save's tab-completion only ever enumerated schema-backed
identifiers; kglobalshortcutsrc identifiers never showed up as
candidates despite being a fully supported mechanism. Enumerate them
live via kglobalaccel (allMainComponents/allActionsForComponent),
printed as a separate block after the schema-backed one, degrading
silently if the D-Bus session is unavailable.
