build(core): exclude src if feature not available

- exclude authenticate_device if Optiga not present (i.e. T2T1)
- exclude set_backlight if backlight feature not available (i.e.
T2B1/T3B1)
- the handlers for these files were already correctly excluded from
`workflow_handlers.py`

The short version

What changed, and why it matters

This is a routine build-system cleanup for the Trezor hardware wallet firmware. It makes sure that certain device-specific source files (for example, code that talks to a security chip called Optiga, or code that adjusts screen backlight) are only included in firmware builds for devices that actually have those hardware features. There is no indication this fixes a security vulnerability or changes runtime behavior on supported devices.

Recommended action

No security action required. Treat as normal build maintenance.

Security signals we found

No strong security signals were identified.

chore(core): remove sha1 from regular FW

This commit removes the SHA-1 hashing function from the regular Trezor firmware. SHA-1 is an old, weak hash algorithm that is no longer considered secure for sensitive uses. The change deletes the code that exposes SHA-1 to apps running on…

refactor(crypto): pass static public key to `noise_xxpsk3_*_init()`

This commit changes how a cryptographic library sets up secure connections. Previously, the code automatically calculated the public key from the private key. Now, the caller must provide the public key directly. This is a code-quality ref…

Cryptographic key handling changed: public key is now supplied rather than derivedPotential reduction of key-mismatch risk if caller provides correct public keyNew null-pointer check added for static_public_key

refactor(crypto): change order of parameters

This commit simply reorders the arguments of an internal function called dh() and updates every place that calls it. The actual math and security behavior are unchanged; it is a code cleanup with no security effect.
