refactor(disable): reduce complexity of run() in disable.rs (#1489)

Extract ApplyOutcome enum and apply_action() helper so the per-definition
loop body is a flat three-arm match instead of nested match-if-match.

- New: ApplyOutcome { Skipped, Patched, Failed } enum
- New: apply_action() — handles one Action, prints status, returns outcome
- run() loop reduced from ~25 lines of nested control flow to 6 lines
