Let the screen own its settings, answer its pings, and show them as cards (0.2.57)

A code check found that a setting changed on a screen could jump back.
ESP Screen Manager kept its own copy and sent it with every full update:
after a restart of the app or Home Assistant, every hour and after every
save. A change it missed while it or Home Assistant restarted came back
to the old value, a reported setting was lost when save() refused a
layout with a removed entity, and every step of a held - or + on the
screen resent the whole screen.

Firmware 0.2.49 offers every setting as an entity over the existing
preference records (no migration): Night mode, Night starts/ends,
24-hour clock, Back to page 1 and after how long, Back to page 1 on
standby, Swipe between pages and, on the Guition, Rotation, next to the
four numbers and Auto standby. The settings page and every entity write
through settings_screen::set(), which clamps like the page and stores,
applies and reports only a real change. screen_message answers a caller
that asks with its status and layout revision (api.respond). The
settings tile opens without Home Assistant.

The app reads and changes the settings of such a screen through its
entities and leaves them out of the layout message. Older firmware keeps
them with the layout; a setting it reports is stored without the tile
check and not sent back. Pings to screens that can answer learn at once
whether a tile is missing and resend after 30 s instead of 120 s. Layout
sensors come back after a Home Assistant restart, and weather tiles only
ask for the forecasts the entity supports. The editor's settings form is
now three cards with the rows of the screen's own page; a change applies
at once, and an offline screen shows its values as unknown.

Checked with 245 Python and 14 C++ tests, generate_packages --check,
ESP32 builds of both profiles, host-build API tests on both boards, and
a live run against Home Assistant 2026.9.1 with a temporary host device.
Firmware 0.2.49.
