Extract common applet pattern (no-icon dmenu layout) into applet.rasi.
Reduce clipboard, vpn, cpugov, volume, and bluetooth themes to pure
overrides — eliminates ~380 lines of duplication. Also fixes broken
fonts.rasi import in bluetooth.rasi.
Clipboard-History (Super+C) nutzte bisher rofi ohne Theme.
Neues clipboard.rasi und moonarch-clipboard Script analog zu
den anderen Rofi-Menüs (vpn, volume, session etc.).
