XML: render dark/light modes in a single paparazzi snapshot instance.

[kanake10]

Goal

Dark and light mode snapshots in PaparazziViewTest were not rendering correctly. Both halves of the combined snapshot appeared identical because createConfigurationContext is ignored by Paparazzi, so the night mode flag had no effect.

Implementation

Replace createConfigurationContext with paparazzi.unsafeUpdateConfig, passing a DeviceConfig with the correct NightMode before each view is inflated.

Walkthrough

PaparazziViewTest is refactored to toggle Paparazzi's device night-mode configuration at runtime using paparazzi.unsafeUpdateConfig with a new applyNightMode helper and overridable baseDeviceConfig property, replacing the previous separate light/dark context approach.

Changes

Runtime Night-Mode Snapshot Support

Layer / File(s)	Summary
Imports and baseDeviceConfig property stream-chat-android-ui-components/src/test/kotlin/io/getstream/chat/android/ui/PaparazziViewTest.kt	Adds DeviceConfig and NightMode imports and introduces the open val baseDeviceConfig property (defaulting to DeviceConfig.PIXEL_4A) as the baseline for night-mode config copies.
applyNightMode helper and snapshot flow stream-chat-android-ui-components/src/test/kotlin/io/getstream/chat/android/ui/PaparazziViewTest.kt	snapshot now calls applyNightMode before capturing. snapshotLightAndDark builds lightView and darkView by toggling night mode between viewFactory(paparazzi.context) calls. applyNightMode drives the change via paparazzi.unsafeUpdateConfig(baseDeviceConfig.copy(nightMode=...)).

Poem

🐇 Hop hop, the night falls and rises with ease,
No more two contexts to juggle and please.
One config to copy, one flag to flip true,
Dark views and light views now rendered anew!
I snapshot the world in both moonlight and sun~ 🌙☀️

Thanks for working on this. The approach is right: createConfigurationContext is ignored by Paparazzi, so calling unsafeUpdateConfig before each inflation is the correct way to do it, and the regenerated header golden confirms light and dark now render together.

One blocking issue: the device config is set in two places that can differ, so one test renders on the wrong device. I left the details inline. After the fix, the affected goldens need re-recording. Nothing else is required to merge.
