🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Expand regression coverage for folder expansion.

Assert that the folder-children request sends srctype=message, the expected srcid, and recursive=false. Also add converter-level tests covering successful expansion and flat-folder fallback when runtime context is unavailable or the API call fails, so reverting the changed conversion branch makes the tests fail.

In `@shortcuts/im/convert_lib/folder_test.go` around lines 43 - 47, Add tests for
folderConverter.Convert covering successful folder expansion and flat-folder
fallback when runtime context is unavailable or the API call fails. Exercise the
new Convert branch directly rather than only fetchFolderChildrenTree, and ensure
the tests fail if that branch is reverted.

Apply the same fix in `@shortcuts/im/convert_lib/folder_test.go` at line 30.

Project the folder-children response into typed structs.

DoAPIJSONTyped returns map[string]any, and this function silently ignores failed assertions for items and item fields. A malformed response can become an empty result or XML elements with empty attributes. Define local typed response and item structs at this boundary.

fetchFolderChildrenTree to define local typed response and item structs, then
decode the DoAPIJSONTyped result into those structs before projecting the folder
children. Replace unchecked items and item-field assertions with typed fields
and preserve the existing output behavior for valid responses.
