Update Chainlink Driver BOM and placement data (#251)

* Add missing BOM part numbers to avoid JLCPCB randomly picking very
wrong components for unspecified BOM entries:
  * Motor JST connectors
  * Sensor pin headers
  * IDC connectors
* Switch back to original screw terminal (C8465) instead of alt
* Permanently switch to alt part (C176661) for 10uF capacitor and fix
placement orientation
* Apply placement corrections as needed (Fixes #225)

Checked on JLCPCB:
