Let Home Assistant automations switch Auto standby per screen, and teach the skill (0.2.48)

App 0.2.48 / firmware 0.2.41:
- Both boards expose the switch "Auto standby", the same standby_enabled setting as the checkbox
  in ESP Screens. Off wakes a dimmed screen and keeps it on; on counts the standby time from that
  moment. The change is saved on the screen and reported through esphome.screen_setting, so ESP
  Screens stores it too. No action runs at boot (restore_mode DISABLED).
- The Claude skill gains "Standby and brightness": the switch, Standby after and the three
  brightness numbers, with an example automation that keeps screens awake while someone is home
  and a light is on or a window is open.
- EASY_SETUP and the README describe the entities and the automation.

Tested through Home Assistant's API on both bench boards (CYD: dimmed -> off wakes in 1.1 s, stays
bright past the standby time, on dims again after 61 s); see docs/TEST_RESULTS_0248.md, which also
records a CYD rollback after the first OTA that points to memory headroom, not to this change.
