Make page swipes smooth and give lights a new colour card (0.2.42)

Browse Source 
Page switches show the new page as empty cards at once and draw two cards per
LVGL refresh, so touch is polled between the steps; on the Guition the longest
loop gap during a swipe dropped from 276 to 74 ms (docs/SWIPE_PROFILE.md).
Custom parts and control panels are reused instead of rebuilt, state updates
and ticks redraw only their own card, clocks redraw once a minute, and a swipe
past the last page draws nothing.

Slider handles sit inside the fill (grey when the card is off), the busy sheet
covers the whole card, and the light colour card is redesigned with rounded
tracks and colour knobs. Firmware 0.2.36; SWIPE_PROFILE builds carry a
per-swipe profiler for measurements.

The `MDI_GLYPH_*` substitutions are retired: `TILEn_ICON` in manual
profiles must come from the set. No changed preferences or keys.
### Compatibility 0.2.42 / firmware 0.2.36
Firmware only: storage version, tile protocol, preferences and keys are unchanged. What moved
inside `runtime_tiles.h` (measurements in docs/SWIPE_PROFILE.md):
- `render()` is split into `render_slot()`. A page switch (`show_page` to another page) places
the page, shows every card as a skeleton (a sheet in the card colour over its content area,
`Widgets::veil`) and draws two cards per LVGL refresh (`fill_cards`, `FILL_STEP_CARDS`,
`LV_EVENT_REFR_READY`, 40 ms fallback); a new switch cancels the fill. `apply_page` (same page:
keepalives, re-packing) still draws everything at once. `check_tile_geometry` finishes a fill
still under way and logs `page fill still under way at the check`.
- `refresh_tile(index)`, `refresh_header_only()` and `refresh_all()` mark what the next
`render()` draws; a plain `refresh()` from the board YAML draws every card, as before.
- A slot hides custom parts and control panels instead of deleting them and reuses them for the
same kind (`hide_extra`, `hide_panel`); `end_extra`/`end_panel` still delete on a kind change.
- Guarded style setters `set_color`/`set_number`; card content sizes from the styles
(`tile_width`, `content_width`, `content_height`) instead of `lv_obj_update_layout()`.
- Card sliders: `slider_handle()` narrows the knob and moves it back into the fill and sets the
range to `-below..1000`, so 0 still shows one round end; `slider_event` keeps values at 0 or
above, `commit_slider` clamps as before. Off cards get a grey fill.
- The busy sheet is sized from the requested card width and kept as the tile's last child.
- `show_page` ignores a request past the first or last page when that page is already shown.
- `tick()` redraws clock cards when the minute changes.
- `light_controls::setup(parent, font, width, height, icon_font)`: the icon font is new and
optional; both board profiles pass `materialdesign_icons_mini` (the glyphs palette,
thermometer and lightbulb are already in the tile icon set). Rows, sliders, `open()` and
`self_test()` keep their behaviour; the brightness range starts below 1 for the same round end.
- `swipe_profile.h` and the `swipe_test` message exist only with `-DSWIPE_PROFILE=1`; release
builds and packages never set it.
### Compatibility 0.2.41 / firmware 0.2.35
Storage version and tile protocol stay 1. Firmware 0.2.35 only raises
