[MOR-1646] IC-7300 CW Pitch, Key Speed, and Break-in writes must not report stale radio truth

Problem

On IC-7300 desktop validation, CW Pitch and Key Speed gestures dispatched writes but fresh canonical radio state returned their prior values. FULL was also observed enqueuing a break-in mode write; it must be verified independently rather than inferred from the other controls. The UI must not present successful control behavior when execution or confirmation has not occurred.

Acceptance criteria

• CW Pitch and Key Speed: one gesture results in one correctly routed IC-7300 CI-V write and bounded canonical confirmation of the requested value, or a truthful rejected/unconfirmed result.
• FULL and SEMI break-in mode intents are independently covered; the observed FULL enqueue is not proof that SEMI works.
• Use existing state/acquisition authority; no optimistic radio truth, extra polling loop, or model-name frontend branch.
• Focused exact-profile tests cover command route and post-write outcome; a non-mock IC-7300 profile witness covers command mapping.
• A hardware rerun records final confirmed value/mode after one gesture.
• PTT/TUNE and all transmit behavior remain out of scope.
