fmt: fix Trunk Check lint issues on nrf54l15-port

- extra_scripts/nrf54l15_linker.py: move regular imports above
  Import("env") to silence E402, add trunk-ignore-all(F821) for the
  PIO/SCons SConstruct injection (matches esp32_pre.py / nrf52_extra.py
  convention)
- src/platform/nrf54l15/NRF54L15Bluetooth.cpp: clang-format 16.0.3
- boards/nrf54l15dk.json + variants/nrf54l15/nrf54l15dk/README.md:
  prettier 3.8.3 (also resolves markdownlint MD060 on README tables)

No behavior change.
