Fix flaky image_store_io_test "without picker copies everything is copied"

what

test/attachments/image_store_io_test.dart "attachFile without picker copies everything is copied" fails about 1 run in 4 under parallel load with PathNotFoundException: Cannot retrieve length of file from ImageCacheStore._run (lib/images/image_cache_store.dart:135). The test returns while IoImageStore.attachFile still has its fire-and-forget unawaited(_sync(const {})) running; teardown deletes the temp root and the upload pass calls file.length() on a file that existsSync() just saw. Predates the AccountManager branch (no file in lib/images, lib/attachments or test/attachments was touched). Seen once as 591/592 and once with --reporter expanded at 635/636.

done

for i in $(seq 20); do flutter test test/attachments/image_store_io_test.dart --concurrency=4 || exit 1; done exits 0, and the production path tolerates a file vanishing mid-pass (skip it instead of throwing).

verify

Same loop on this repo; plus the full suite ends with "All tests passed!".
