Symbol-Picker als Satellite-Fenster (statt Modal im Elemente-Panel)

UX-Verbesserung: Modal-Overlay im engen Elemente-Panel war unpraktisch.
Symbol-Picker oeffnet sich jetzt als eigenstaendiges Eto.Form-Fenster
(wie Library/Project-Settings).

Frontend:
- SymbolPicker bekommt embedded-Prop (Satellite-Mount vs Modal-Overlay)
- Neuer SymbolPickerApp Satellite-Wrapper (PANEL_PARAMS lesen + Bridge)
- main.jsx: 'symbol_picker' Mode-Routing
- ElementeApp: Symbol-Button ruft nur noch listLibrary() — Backend
  oeffnet das Fenster

Backend:
- _cmd_list_library oeffnet jetzt das Satellite-Window mit eigener
  Bridge (PICK -> CREATE_SYMBOL, CANCEL -> Close)
- PICK schliesst Fenster + triggert interactive GetPoint im Viewport
