Let every screen choose its top bar: clocks, date and entities (0.2.38)

The name stays on the left; up to six items go on the right: the time, an
analog clock, the date, or a Home Assistant entity with its icon, showing its
state or how long ago it changed, always or only while active. The add-on
formats entity text in Dutch and sends it as op: header right after the layout
to firmware 0.2.32+; older firmware keeps the clock of show_clock, which now
follows the clock item.

The firmware draws every value in one font on the name's baseline, centres
icons and the dial on the digit height and measures gaps between glyph ink, so
the bar looks even; the editor's mockup uses Roboto and the same integer rules.
tools/render_topbar.py renders the real LVGL code on a computer (ESPHome host +
SDL2). The editor's section buttons are gone.

Firmware 0.2.32 for both boards.
