Fix what a full test round of today's releases found: a ticking single clock, a switch that works in standby, no taps from a swipe (0.2.78)

A test and code-analysis round of 0.2.72 to 0.2.76 (suites at every tag, sanitizers, ESP32 and GitHub builds, host
harnesses on both boards, the editor in a browser, best practice checked against ESPHome, LVGL, Home Assistant and
Vue) found these, fixed here with Max's choices for the product questions:

- Firmware 0.2.65: the second hand of a single analog clock moves again; on a page that is one full on/off tile the
  waking push also switches it; on the Guition a flick is never a tap and a finger that slides off a tile doesn't tap
  it; Previous/Next react to a firm press; the same Go to page tile may sit on several pages; a layout the screen has
  no memory for is refused instead of crashing; 64-bit redraw mask for 48 tiles; Montserrat 14 no longer built.
- App: Save refuses a layout too long for one message or too big for eight pages; an offline screen keeps its
  firmware version from the device registry; HA refusals reach the editor; 128 KB requests; changelog out of the
  live stream; cached hashed assets; tini as init and a clean stop; changelog parsing without asterisks or crashes.
- Editor: clicking the open screen keeps unsaved edits, edits during a save stay unsaved, a Page row and phone
  dragging to other pages, repeated page tiles, limits from the server, HA's error messages, a type-checked build.
- tools/check.sh + GitHub Actions + a CYD flash budget; docs match 48 tiles and the new editor.
