Second hand on the analog clock, sliders like Home Assistant's, one top bar on every card (0.2.43)

Firmware 0.2.37 for both boards:
- The analog clock card gets a thin red second hand that moves every second while the
  screen is awake (runtime_tiles::screen_awake, set by the profiles from display_dimmed);
  in standby it hides and the clock keeps its once-a-minute redraw.
- Card sliders follow HA's control slider: 12/42 and 8/42 corners, a 4 px handle an
  eighth of the height from the fill end, a stub of a third of the height at 0 or 1 %,
  the track in the fill colour at 20 %. An off light or fan shows only the empty grey
  track, also in the colour card's brightness row. A light's slider floors at 1 %.
- Every overlay card shares one top bar: a round back arrow at the left (60/40 px), the
  name centred, and only the climate power as a right-hand action. The "done"/"ok"
  buttons of the colour and vacuum cards are gone; the brightness card gets its arrow.
- The top bar reads "Connecting to Home Assistant..." / "Waiting for ESP Screens..."
  until the first layout, instead of "Choose tiles in HA".

Checked with the host renderer for both boards and on the Guition over USB.
