Adeeb Shihadeh 45151243fb Fix infinite loops and timeout handling in SPI and CAN ...

- SPI _wait_for_ack: default timeout=0 to 500ms, clamp to 100-500ms range
- SPI _transfer: default timeout=0 to 500ms, add MAX_TIMEOUT_RETRIES (5) limit
- SPI _transfer: add NACK backoff like C++ implementation
- SPI _transfer: run recovery logic for ALL exception types (fixes onroad test)
- CAN can_recv: max 3 retries instead of infinite loop, return [] on failure
- CAN can_send_many: detect no-progress and drop after 3 retries
- CAN_SEND_TIMEOUT_MS: changed from 10ms to 5ms to match C++

These changes align Python behavior with the C++ pandad implementation.
