chore: organize

use read-made spotifyd module
move sshPort to niveum lib (used also from deploy.nix)
factor out sshd config, use from toum
factor out urlwatch
access scardanelli locally
mpd: configure webradio playlist
scardanelli: use cage for kiosk
toum: use wifi config
toum: use spacetime, dont redeclare
toum: use ssh config
