chore(nordic): update mcuboot
[no changelog]
What changed, and why it matters
This is a routine dependency update for the Nordic chip bootloader component (MCUboot) used in Trezor hardware wallets. The commit only changes one line: it points the build system to a newer commit hash of Trezor's fork of MCUboot. There is no description of any security issue, bug fix, or functional change in the commit message or diff. Without additional information about what changed between the two MCUboot revisions, this single-line manifest update by itself does not demonstrate any security problem.
Review the MCUboot diff between the two revisions (1e6be31a50d92f79eb5bae4a9233c6e71462b800 and 439e4f2a03b99ce2955ea95ff2c691a6f314de4c in https://github.com/trezor/mcuboot) to determine whether the update addresses any security-relevant fixes. If this is a routine chore update, no immediate action is required beyond normal dependency tracking.

Evidence from the diff
The commit updates nordic/trezor/west.yml to change the mcuboot revision from 1e6be31a50d92f79eb5bae4a9233c6e71462b800 to 439e4f2a03b99ce2955ea95ff2c691a6f314de4c, both tagged as trezor-v2.1.0-ncs3. This is a west manifest pin change for the Zephyr/Nordic build. The diff contains no code changes, no changelog entry, and no security notes. The security relevance of the underlying MCUboot delta cannot be assessed from this commit alone.
