Forty-eight tiles, a tile over the whole page and tiles that go to a page (0.2.74)

Max asked for many more tiles, a tile that takes the whole page as a light
switch you push without looking, and tiles that go to a page. The limit is
one tile per slot of the eight pages, 48, and the firmware keeps its tile
list on the heap sized to the layout (PSRAM on a Guition). A tile's size can
be `full`: one big button that lights up in the state colour while on, or the
double-width card's head with its small slider, direct controls or graph at
the bottom and the value the double-width card had no room for in between;
the clock, the forecast (with an hours strip) and the sun path fill the page.
Navigation tiles are the built-in entities screen.page_1 to screen.page_8:
an arrow or a chosen icon, the name and "Page n", a tap opens that page.
The app sends the three only to firmware 0.2.62+, the editor (the Vue port of
this round by the editor session, 00c9a4e) offers Normal / Double-width /
Full page and "Goes to page", and Claude in Home Assistant gets size: full and
the page tiles. Built-in tiles now send a chosen icon as its codepoint.

Found and fixed by the new host harness before release: the one-second tick
moved the analog clock's second hand (part 18) on a full forecast's hour label
during a page switch and corrupted it. Firmware 0.2.62; both C++ and Python
suites, host harness 37/37 on both boards, hardware pass on both bench boards
in docs/TEST_RESULTS_0274.md.
