install.sh: restart capture services instead of enable --now

enable --now only starts a service that is not yet running — it leaves
an already-running service untouched, so changes to .env credentials
are never picked up without a manual restart.

Switching to enable + restart means every install.sh run brings capture
services in sync with the current sky-cam.conf and .env: new cameras
start, reconfigured cameras restart, and nothing needs manual follow-up.
