Put ESP Screens in English and keep layouts when entity IDs change (0.2.40)

Everything a user sees or reads is now English: both boards' labels,
status replies and logs, the ESP Screens editor and Alerts cheatsheet,
and the README and guides (docs/TILES.md, CALIBRATING.md, ACCEPTANCE.md
and TROUBLESHOOTING.md replace the Dutch file names). Labels follow
Home Assistant's own English names (Heat/Cool modes, Heating/Cooling
actions, Away, Returning to dock, weather conditions), dates use English
abbreviations and the top bar writes numbers the English way. Docs use
HA 2026.9's menu names (Settings -> Apps, App store, Settings -> Tools).
Unused legacy files (home-like.yaml, buttons.yaml, a.out) are removed.

Firmware 0.2.34 names its entities in English. Home Assistant registers
a renamed ESPHome entity under a new entity ID, so the inbox
text.<screen>_tegelinstellingen becomes text.<screen>_tile_settings and
the layout stored under the old ID would be lost. The manager now
recognises the screen by its device, during a run or after a restart,
and moves its layout and update history along; the Update button and
the nightly round follow the screen through the rename. Screens that
still run 0.2.33 or older keep working: both languages are matched.

Main is the only release branch from now on.

Tested on a Home Assistant Yellow (HA 2026.9.1) with both bench boards:
see docs/TEST_RESULTS_0240.md.
