chore: add QA bootloaders
(cherry picked from commit 366fd6cc2ad7493788cd1db19ae238b2c83fe7a7)
What changed, and why it matters
This commit updates a QA/testing bootloader binary and its recorded cryptographic hash for the T3W1 hardware model. It is a routine development chore with no visible security fix or vulnerability.
No security action required; treat as routine QA asset update. If desired, verify the new devel bootloader hash against the built artifact in CI.
Security signals we found
No strong security signals were identified.
Evidence from the diff
The change replaces the bootloader_T3W1_devel.bin binary and updates the corresponding SHA-256 hashes in bootloader_hashes.h from version 2.1.16.0 to 2.1.17.0. The diff only shows a binary blob replacement and hash refresh; no source code, security patch, or vulnerability description is present.
