[js051]

Summary

• add capability-gated Canon CCAPI /functions/beep and /functions/displayoff controls across Android, iOS, PC and Simulator
• require exact same-version GET/PUT pairs, strict documented abilities and a fresh pre-write read
• localize English/Traditional Chinese UI and expose the controls in Photo and Video More Settings, including offline preview
• add direct-client, malformed/stale/cross-version, Compose, Android Simulator and Playwright browser coverage
• document physical R6 Mark III validation as still required and keep immediate auto-power-off out of this ordinary setting flow
