diag: per-publisher valid=False logging; 30min shutdown; daylight fix; UI tweaks

CLAUDE.md: added a "Logging" rule — never use cloudlog (upstream cloud
pipeline, effectively a black hole for us), always use
print(..., file=sys.stderr, flush=True). Manager redirects each process's
stderr to /data/log2/current/{proc}.log. Prefix our lines with "CLP ".

Diagnostic logging — when a publisher sets its own msg.valid=False, log
which specific subscriber tripped the check. Only fires on transition
(True→False) so we don't spam. Covers the services whose cascades we've
been chasing:
  - frogpilot_planner (frogpilotPlan)
  - longitudinal_planner (longitudinalPlan)
  - paramsd (liveParameters)
  - calibrationd (liveCalibration)
  - torqued (liveTorqueParameters)
  - dmonitoringd (driverMonitoringState)

gpsd.is_daylight: fixed a day-boundary bug where the function would flip
to "night" at UTC midnight regardless of actual local sunset. At 85W
sunset is ~00:20 UTC next day, so between local 8pm and actual sunset
the function used *tomorrow's* sunrise/sunset and said night. Now checks
yesterday/today/tomorrow windows with UTC-day offsets.

ui/onroad.cc: nightrider tire-path outline is now light blue (#99CCFF)
at 3px (was white/status-tinted at 6px); lane lines 5% thinner (float
pen width).

thermald/power_monitoring: auto-shutdown timer 10min → 30min.
