Add support for Puya PY25Q128HA flash chip

The Puya PY25Q128HA is a W25Q128-compatible 128Mbit (16MB) SPI NOR flash
chip. This PR adds detection support by including its JEDEC ID in the flash
configuration table.

Changes:
- Added PY25Q128HA JEDEC ID (0x856018) to m25p16FlashConfig[] array
- Updated Blackbox documentation with PY25Q128HA in supported chips list

The chip uses the same SPI command set as other supported flash chips,
so no driver modifications are required beyond adding the JEDEC ID for
auto-detection during initialization.
