🧹 Refactor: Extract Action formatting logic to resolve overlong function

[undivisible]

🎯 What: Extracted the formatting logic for the largest variants of the Action enum into private helper methods (fmt_click, fmt_type_text, fmt_press, fmt_application, fmt_window, fmt_open).
💡 Why: The original fmt implementation was an overly long 92-line function triggering code health warnings. By delegating complex formatting blocks to helper methods, the main fmt function is concise and readable. The refactoring preserves Rust's powerful compile-time exhaustiveness checking by maintaining a single match block without wildcards or catch-alls.
✅ Verification: Ran cargo check, cargo clippy, and the full test suite (cargo test --all-features) in an isolated environment. The behavior of the Debug formatter is identical, maintaining all &"[redacted]" privacy measures.
✨ Result: Improved maintainability, eliminated the code health warning, and retained exhaustive pattern matching for safety.

Note

Low Risk
Refactor of Debug formatting only; no runtime, API, or security-logic changes beyond existing redaction.

Overview
Shrinks the oversized Debug implementation for Action by moving formatting for Click, TypeText, Press, Application, Window, and Open into private fmt_* helpers on impl Action.

The main match in fmt now delegates to those helpers instead of inlining large debug_struct blocks. Redacted fields (text, key, app names, etc.) and non-sensitive fields stay the same—this is a structure/readability change only, not a behavior change.
