applet.interface.spi_controller_deprecated: remove.

applet.display.pdi: remove.

This is a V1 applet using the deprecated SPI controller, and it would
require a non-trivial migration effort. I still have the device against
which it was written, but given how obscure this early EPD is, it feels
unlikely that this applet serves anyone's needs.

We do not often remove applets but this one seems like a good choice
for removal.

applet.program.nrf24lx1: migrate to V2 API.

Also, add some (non-exhaustive) hardware-in-loop tests.

applet.radio.nrf24l01: migrate to V2 API.

Also, add interface documentation.

applet.interface.spi_controller: make `mode` an argument of `SPIControllerInterface`.

- [github.com/astral-sh/ruff-pre-commit: v0.14.14 → v0.15.0](https://github.com/astral-sh/ruff-pre-commit/compare/v0.14.14...v0.15.0)

[pre-commit.ci] software: automatic code style fixes.

For more information, see https://pre-commit.ci.

applet.program.avr.spi: migrate to V2 API.

Also, make programming entry procedure closer to what's described
in the datasheet.

Also, switch tests to ATmega328P, since that's much more common.

applet: fix bitrot around v2 hardware-in-loop tests.
