PCB rework: place and route MDI termination + FTDI EEPROM resistors

Browse Source 
Rework by Dennis; reviewed with DRC 0 errors / 0 unconnected / 0 parity:
- R26-R29 + C18/C19 at U11's MDI edge (1-3mm from pins), short stubs,
  ETH_DP impedance rules pass, pair skew TX 0.30mm / RX 0.72mm
- D4/D5 true flow-through (PHY side faces U11, cable side faces J2)
- In1 GND plane voided under the magjack cable/isolation side
- R30/R31 placed at U7; 30 GND stitch vias in the ethernet corner
