BalancedDef and PowersaverDef set to -1 in all configs effectively disables lpmd when power-profiles-daemon is running

All shipped configuration files set -1 and -1, which forces lpmd OFF for both the "balanced" and "power-saver" power profiles. Combined with -1, this means lpmd is unconditionally disabled whenever power-profiles-daemon
(PPD) is running.

Since PPD is active by default on most modern Linux desktop environments (GNOME, KDE), and the default profile is "balanced", lpmd will never engage on a typical installation.

The daemon only becomes active when PPD is not installed, because connect_to_power_profile_daemon() failure causes a fallback to LPMD_AUTO in lpmd_proc.c.

### Expected behavior

For mobile/laptop platforms where lpmd is designed to save power, more useful defaults would be:

- PerformanceDef=-1 — keep lpmd off when user explicitly wants maximum performance (correct as-is)
- BalancedDef=0 — allow lpmd to opportunistically enter/exit low power mode based on WLT hints and utilization
- PowersaverDef=0 — same as balanced, or potentially 1 (force on) to aggressively save power

This way lpmd actually participates in power management on systems where PPD is running, which is the common case on desktop Linux distributions.
