feat(vnc): Fn-Steuertasten-Leiste + Enter-Fix fuer VM-Bedienung
Die Software-Tastatur liefert weder Enter (Haken) noch Esc/Pfeile/F-Tasten/ Strg/Alt. Neu: - Haken der Tastatur → onSubmitEditing sendet jetzt Enter (returnKeyType=send). - Fn-Leiste (Toggle in der ctlBar): Esc, Tab, Pfeile, Pos1/Ende/Bild, Einfg/ Entf, Enter, F1–F12, Strg+Alt+Entf — direkt an rfb.sendKey. - Sticky-Modifier Strg/Alt/Shift (one-shot): kombinieren mit der naechsten Taste ODER dem naechsten getippten Zeichen → Strg+C, Strg+Alt+Entf, Alt+F … - noVNC: window.ariaVncKey.combo(mods,ks) haelt Modifier, tappt, laesst los.
