chore(core): update T3W1 embedded bootloader QA
What changed, and why it matters
This commit swaps in a newer QA (quality assurance) bootloader binary for the T3W1 hardware model and updates the matching hash table used by the firmware to recognize it. The change is labeled as a routine chore with no changelog entry. There is no information in the commit or supplied references indicating this fixes or introduces a security problem.
No security action is required based on this commit alone. If auditing the bootloader update, retrieve and compare the 2.1.13.0 and 2.1.14.0 bootloader source/build artifacts to confirm the QA-only nature of the change and verify the new hash.
Security signals we found
No strong security signals were identified.
Evidence from the diff
The diff replaces core/embed/models/T3W1/bootloaders/bootloader_T3W1_qa.bin with a new build (version comment updated from 2.1.13.0 to 2.1.14.0) and updates the corresponding SHA-256 constants BOOTLOADER_T3W1_QA_00 and BOOTLOADER_T3W1_QA_FF in bootloader_hashes.h. The production bootloader hashes (BOOTLOADER_T3W1_00/FF) are untouched. The embedded bootloader blob is opaque in the diff, so the exact code changes inside it cannot be reviewed from this commit alone.
