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.

+## 0.2.74 (firmware 0.2.62)
+
+Forty-eight tiles, a tile over the whole page, and tiles that go to a page.
+
+- **Up to 48 tiles per screen**, one for every slot of the eight pages (twenty before). A screen only pays for the tiles it has: the firmware keeps a list as long as the layout instead of a fixed twenty, and on a Guition that list lives in PSRAM.
+- **Full page.** A tile's size can now be *Full page*: it takes all six slots of a page and is one big button, so a screen on the wall next to the door switches the light when you push anywhere on it, without looking. While the light is on the whole card lights up in the state colour (amber for a lamp, purple for a scene, blue for a blind), so you see from across the room whether it is on. Holding it still opens the card. A small slider, direct controls or a graph sit at the bottom of the page, big enough for a thumb; the room above them is still the button. The clock, the weather (now with the next hours under the days) and the sun path fill the page. A tile you make full-page keeps its page: the other tiles there move to the first free spots after it.
+- **Go to page.** A new built-in tile, *Go to page*, opens the page you choose: an arrow (or an icon of your own), its name and the page number, with a chevron like the rows in Home Assistant's settings. Put a full-page light switch on page 1 and a menu of *Heating*, *Blinds* and *Vacuum* on page 2, each with its own page.
+- Claude in Home Assistant can do the same: `size: full` on a tile, and `screen.page` with `to_page` for a navigation tile. The screen's sensor reports both.
+- Needs firmware 0.2.62: press **Update** on the screen. Includes everything from 0.2.73.
