fix(ios): physical-device install lost devicectl hints; delete the dead install/uninstall/push paths #2785

Purpose

#1758 (66cca1a) moved physical-device install to packages/platform-apple/src/deployment/runtime.ts:137-148. That code checks devicectl with the local assertAppleToolSuccess (:214-224) and never calls resolveIosDevicectlHint (core/devicectl.ts:365). Since then, physical install failures have not shown the Developer Mode, DDI and pairing hints that #1527 and #2690 added. Other devicectl paths still attach them (deployment/runtime.ts:81/266, core/physical-device-coredevice.ts:483, core/perf.ts:1095).

The old implementations are now dead:

• installApp, uninstallApp and assertAppInstallationSupported in packages/platform-apple/src/core/physical-device-control.ts:45-130 have no callers.
• pushIosNotification (core/app-device-io.ts:42-61) is test-only. deployment/runtime.ts:176 replaced it.

Line references are at 01328de411.

Required behavior

• Physical install and uninstall in deployment/runtime.ts attach the same hint that resolveIosDevicectlHint produces for other devicectl failures. Route the call through runIosDevicectl, or call the resolver on failure. Keep the typed details.
• Delete the dead functions listed above, their tests, and the declaration at test/integration/command-coverage/declarations.ts:512.
• Keep physical-device-facade.ts and the physical-device-apps functions. They are live package exports that three daemon modules use.

Completion conditions

• A unit test covers a devicectl install failure whose stderr shows Developer Mode is disabled. It asserts that the hint appears in the normalized error.
• pnpm check:production-exports and pnpm check:fallow are green. Move baseline entries; do not regenerate them.
• pnpm check:affected --run is green.
