Rewrites the Keycard integration to talk to the LEE-flavored applet directly from Rust via keycard-rs (pinned git dependency), dropping the pyo3 shim, python_path.rs, and the vendored keycard-py Python library entirely. Verified end-to-end against real hardware: pairing, PIN verification, mnemonic loading, BIP340 Schnorr signing, and transfers between keycard and public/private accounts. Also cleans up the pyo3 usage that had leaked into wallet's signing path (signing.rs, account_manager.rs) beyond the keycard CLI itself, and trims wallet_with_keycard.sh's Python setup down to just pyscard, which is only needed by the force_unpower.py test helper now.

"""
|
|
Forces the card in the first available reader into the unpowered state via
|
|
PC/SC SCARD_UNPOWER_CARD. Run immediately before a wallet command to simulate
|
|
the power-loss condition reported on some USB reader/driver combinations.
|
|
|
|
Either:
|
|
- pcscd re-powers the card on the next SCardConnect, so wallet
|
|
commands will succeed without triggering the retry path.
|
|
- the card stays unpowered, triggering a PC/SC transport error
|
|
(keycard_rs::Error::Io) and exercising the reconnect-and-retry wrapper in
|
|
KeycardWallet::pair() / KeycardWallet::setup_communication_with_pairing().
