* fix(mobile): downscale oversized clipboard images so paste no longer fails

Pasting a large clipboard image (high-res screenshot or photo) failed with
'Image too large to paste' because the re-encoded PNG exceeded the 24 MiB
base64 upload cap, with nothing shrinking it first.

Now an oversized image is downscaled to fit the budget before upload:
- computeMobileClipboardImageDownscale() picks target dimensions by area
  (~sqrt(budget/actual)), with a bounded retry loop since PNG size is nonlinear.
- prepareMobileClipboardImageBase64() drives the loop with an injected resizer,
  so the byte/dimension logic is unit-tested without native modules.
- The resizer stages the image to a temp file and hands ImageManipulator a
  file:// URI; the iOS native loader (Data(contentsOf:)) cannot decode large
  base64 data URIs, so a data URI made renderAsync throw.

Adds expo-image-manipulator and expo-file-system.

* fix(mobile): fail fast when resized clipboard image has no base64

Empty base64 from saveAsync would pass the downstream base64 check and
upload a corrupt image; throw instead so the paste surfaces an error.

Addresses CodeRabbit review on #5601.

* Fix mobile clipboard image resize cleanup
