refactor(core): fix renamed micropython modules

E.g. uos was renamed to os, uerrno to errno.

Relevant micropython commits:
45ac651d1a2801bccbdc32fddaa9b029ed4ce879 all: Rename *umodule*.c to remove the "u" prefix.
f5f9edf6457624bf32e71b0c2fdcfbfa5d5753a6 all: Rename UMODULE to MODULE in preprocessor/Makefile vars.

The short version

What changed, and why it matters

This commit is a routine code cleanup that updates Trezor firmware to match a newer MicroPython version where built-in module names dropped the 'u' prefix (for example, 'uos' became 'os' and 'ustruct' became 'struct'). It renames imports, configuration flags, and source file references, and removes old mock files. There is no security fix or vulnerability here.

Recommended action

No security action needed. Treat as a normal dependency-compatibility refactor. Verify the build passes with the updated MicroPython module names.

Security signals we found

No strong security signals were identified.

fix(python/trezorlib): enable entropy check on T1 by default

This commit changes the Trezor Python library so that, when setting up a Trezor Model One (the original Trezor 1 device), it now performs an entropy check by default if the device runs firmware 1.13.1 or newer. Previously, the library only…

refactor(core): replace hexlify with bytes.hex()

This is a large but straightforward internal cleanup: the project switched from using the MicroPython `ubinascii` module's `hexlify`/`unhexlify` functions to the standard Python `bytes.hex()` and `bytes.fromhex()` methods. The change remov…

refactor(core): use mp_obj_new_str_from_vstr

This is a code cleanup change in Trezor's firmware that swaps one MicroPython internal helper for another. It replaces calls that create byte or string objects from a vstr buffer with newer, purpose-built helpers. The commit message says t…
