Adds `LilyGo_T-Echo-Lite_non_shell_companion_radio_usb` to
`variants/lilygo_techo_lite/platformio.ini`.

The T-Echo Lite non-shell variant had a BLE companion radio target
but no USB equivalent. This adds the missing USB target, mirroring
the BLE/USB symmetry seen in other nRF52840 devices (RAK4631, Xiao,
T114).

The USB target is identical to the BLE target except:

  • `SerialBLEInterface.cpp` removed
  • `BLE_PIN_CODE=123456` removed
  • `OFFLINE_QUEUE_SIZE=256` removed

Build verified: RAM 40.3% / Flash 51.8%
Hardware tested: T-Echo Lite Non-Shell (nRF52840 + SX1262)
Tested with: Android MeshCore app via USB

Note: This PR adds the non-shell (no display) variant, complementing
PR #2472 which adds the standard T-Echo Lite USB target.
