Should have been done in #7796.
[no changelog]
What changed, and why it matters
This commit removes an unused import of a string type from a Rust source file. It is a routine code cleanup with no functional change and no security relevance.
No action required; this is a benign cleanup change.
Security signals we found
No strong security signals were identified.
Evidence from the diff
The commit deletes a single use heapless::String; import statement from core/embed/rust/src/ui/layout_eckhart/firmware/keyboard/pin.rs. The import was not referenced anywhere in the file, so removing it has no effect on behavior, memory safety, or attack surface. The commit message explicitly labels this as a chore referencing a prior pull request and requests no changelog entry.
