fix: resolve compilation errors and clippy warnings from community PR merges

- config/src/lib.rs: remove undefined has_api_key variable (#2062 conflict)
- ui.rs: clone receipt before move into set_receipt_text
- footer_ui.rs: convert &str to String for if/else type consistency
- rlm.rs: use ref bindings to avoid partial moves of stdout/stderr_preview
- file.rs: prefix unused fuzz variable
- update.rs: remove redundant borrows
- tests.rs: allow print_stderr on catalog metrics test function

All clippy warnings resolved. CI should go green.
