Bring the big climate card to the Guition, with fan and swing on their own card (0.2.47)

App 0.2.47 / firmware 0.2.40:
- guition-4848s040.yaml gets the CYD's climate card: the setpoint between large -/+ keys
  (debounced, hold to repeat) and one row of mode keys in HA's order and colours; the arc,
  scrim, mode pill and climate_number font are gone.
- Fan and swing modes sit right on the card as segmented rows behind their icons, drawn by the
  new climate_card.h (async rebuild, taps through the touch guard and a profile hook). The card
  is laid out per case from one table: no, one or two settings rows, with or without mode keys.
- Both boards hide a mode key row that would hold a single mode and centre the setpoint instead.
- Glyph arrow-oscillating (Home Assistant's swing icon) joins the icon set.

Verified on the Guition over OTA with the owner's air conditioner and with host renders of both
boards; see docs/TEST_RESULTS_0247.md.

+# Test results app 0.2.47 / firmware 0.2.40 (2026-09-15)
+
+The new climate card on the Guition with fan and swing on a card of their own, and no single mode
+key on either board. See CHANGELOG 0.2.47 and RELEASING "Compatibility 0.2.47".
+
+## Automated
+
+- Python (`.venv-portal`): 170 tests OK (the icon tests cover the new `arrow-oscillating` glyph).
+- C++ (`clang++ -std=c++17 -Wall -Wextra -Werror -I . -I components/smart_display`): 13/13 PASS.
+  `climate_card.h` draws LVGL objects and is covered by the host renders below, not by a unit test.
+- `generate_packages.py --check` green, `generate_icons.py --check` verified (150 pickable icons,
+  180 glyphs).
+- ESPHome 2026.6.2 compile SUCCESS, one after another: `easy-guition-device.yaml` (RAM 32.9%, flash
+  18.9%), `easy-cyd-device.yaml` (RAM 32.0%, flash 78.5%), `guition-device.yaml` (RAM 33.0%, flash 20.0%)
+  and `device.yaml` (RAM 32.0%, flash 83.3%). Packages carry `SCREEN_FIRMWARE_VERSION` 0.2.40.
+
+## Bench boards (OTA)
+
+- Both Easy Setup builds uploaded over the network; `device_info` reports project 0.2.40, compiled
+  2026-09-15 15:42:18 (Guition) and 15:44:03 (CYD), matching the build logs. ESP Screens reports both
+  screens Synced on 0.2.40.
+- `preview_runtime_card` opened the climate card of the owner's `climate.airco_remeha_diva_ac` on
+  the Guition with live data from app 0.2.46. The capture (`capture_ui.py`) shows Off with a grey 19°,
+  the five mode keys (heat/cool, heat, cool, dry, fan only), Fan with Low chosen and Swing with Off
+  chosen. The vacuum card of 0.2.46 is unchanged.
+
+## Renders (ESPHome host + SDL, both boards, this release's code)
+
+- Guition climate card in four cases: heating with three modes and a fan row, an air conditioner with
+  five modes, fan and swing (the owner's attributes), the same with two swing modes, and a heat-only
+  thermostat without fan or swing (no mode keys, setpoint centred). Nothing runs off the screen; the
+  card with two rows ends 10 px above the bottom edge.
+- CYD climate card: unchanged apart from the heat-only thermostat, which now shows the centred setpoint
+  without a mode key.
+- `docs/images/guition-climate.png` comes from the air conditioner render.
+
+## Not tested / for the owner
+
+- The Guition climate card by hand: − / + taps and holding, mode keys, fan and swing choices with the
+  real air conditioner (tapping sends real commands).
