fix: CLI dashboard in separate terminal window

Problem: fin_quant overwrites dashboard output

Solution:
- CLI Dashboard (-c) starts in NEW terminal window
- Web Dashboard (-d) runs parallel in browser
- Both combinable: python predix.py fin_quant -d -c

Supported terminal emulators:
- gnome-terminal
- konsole
- xterm
- tilix

Warning displayed if no terminal is found.
