The short version
What changed, and why it matters

This is a routine developer tooling change. Trezor replaced a shell script used to convert certificate files into C header files with a new Python script that does the same job. The actual certificate data did not change, only the wrapper format and build integration were updated. There is no indication this fixes or introduces a security vulnerability.
Recommended action
No security action required. Treat as normal build/maintenance refactor. If reviewing, verify that the new Python generator produces byte-for-byte identical DER output and that `make certs_check` passes in CI.
Security signals we found

No strong security signals were identified.
Technical analysis
Evidence from the diff

The commit removes two gen.sh scripts under core/embed/sec/optiga/unix/certs/ and core/embed/sec/secret/unix/certs/, and introduces core/tools/generate_certificates.py. The generated .h files now use a #define macro (OPTIGA_DEVICE_CERT_CHAIN / MCU_DEVICE_CERT) instead of static const unsigned char ..._der[] plus a length variable. The consuming C code (core/embed/sec/optiga/unix/optiga.c) was updated to use the new macro. The Makefile gained certs and certs_check targets. The DER byte content appears identical between old and new headers; only the C representation and generation tooling changed.
