fix(Android): close temporary image and theme resources

[OskarEichler]

Problems and fixes

The Android resource-lifecycle sweep found two temporary resources that were never closed:

• Dev image loading passed an opened local/network InputStream to BitmapFactory without closing it. If opening or decoding threw, the temporary permissive StrictMode policy also remained installed on the calling thread.
• Modal host measurement obtained a theme TypedArray without recycling it.

This change uses InputStream.use, rejects missing/undecodable streams through the existing error path, restores the original thread policy in finally, and recycles the typed array in finally.

Regression coverage

The new Robolectric regression forces dev-image stream opening to fail and verifies the original network-detecting thread policy is restored. The exact baseline leaves the permissive policy installed.

Verification

• focused regression: 1/1 passed
• full Android unit suite: 698 passed, 2 skipped, 0 failed
• Android debug Kotlin/Java compilation passed
• git diff --check passed

Breaking changes

None. Failed image decoding continues through the existing error callback; resources and thread policy are now cleaned up reliably.
