Retake the README screenshots on 2.10+ (daylight) #197

Since 2.10 (#190) the TV grid plays several cells at full rate again instead of key frames only, so the README screenshots from 2.09 (#186) no longer show the usual picture.

Retake all nine in daylight on the current latest, as described in LABORATORY.md (README screenshots): TV quad_menu, single_status, debug_page/debug_json/debug_log, and phone phone_menu, phone_single, phone_reset, phone_webui.

Planned for 2026-10-16, daytime.
