reset to pre-modification baseline; restart feature work from clean state

Restoring the working tree to the pristine pre-Claude baseline previously
preserved at /data/clearpilot (now /data/clearpilot-baseline). The prior
modified-but-broken tree is snapshotted at /data/openpilot-broken-2026-05-03
and tagged here as pre-reset-2026-05-03 for reference.

From here, features (UI changes, dashcam, telemetry, GPS, display modes,
speed logic, standstill power saving, etc.) will be re-introduced one at
a time with proper testing.
