fix(stats): recreate statistics and card info on rotation

[Ayush-Patel-56]

Purpose / Description

When viewing charts in the Statistics or Card Info screens, tapping on a bar opens a popup tooltip. If the device orientation changes while this popup is active, the popup remains on the screen and goes "out of bounds" instead of updating its position or being dismissed.

Fixes

• Fixes Stats screen "out of bounds" glitch #18358

Approach

Approach

• Switched the hosting activity for Statistics and CardInfoFragment destinations from SingleFragmentActivity to ConfigAwareSingleFragmentActivity. Unlike SingleFragmentActivity, ConfigAwareSingleFragmentActivity recreates on configuration changes (such as device rotation), ensuring the hosting Activity and Fragment are rebuilt and the WebView page is cleanly re-rendered to fit the new screen dimensions.

• Overrode onCreateWebViewClient in Statistics to re-apply the currently selected deck via changeDeck once the WebView finishes loading (using onPageFinishedCallbacks) to preserve the user's selected deck across rotation.

How Has This Been Tested?

Automated Tests

• Updated and ran the local Robolectric unit tests for the statistics screen:
  ./gradlew :AnkiDroid:testPlayDebugUnitTest --tests "com.ichi2.anki.pages.StatisticsTest"
  (Tests pass successfully)

Manual Verification

1. Open the Statistics or Card Info screen.
2. Rotate the device to landscape mode.
3. Tap on a chart bar to display the tooltip popup.
4. Rotate the device back to portrait mode.
5. Verified that the layout re-fits correctly and the out-of-bounds popup is cleared/dismissed.

Configuration: Tested using Robolectric and on an Android Emulator running SDK 33.

Thanks, but your video doesn't seem to demonstrate the fix.

You need to tap on one of the bars in landscape mode to show the tooltip then rotate to portrait mode. Also, the bug is un-noticable when tapping on the bars on the left, so tap the right-mist bar.

I changed the video, and now I think its the correct video as per the issue. btw thanks for tagging the issue.

This now appears to reset scroll position on rotation

[Ayush-Patel-56]

Tried saving and restoring scroll position via webViewLayout.scrollY / webView.scrollTo(), but it's unreliable since we don't know when the SvelteKit charts finish rendering after the reload. Any preferred approach here?

@david-allison can you please help me with this ?
