Bug Description

The tab title shows a raw id instead of the file name for a single file shared with you. Cause: packages/web-pkg/src/composables/appDefaults/useAppDefaults.ts:67 takes the basename of the space path, which is the share id when the item is empty.

Reproduction Steps

1. Open a file shared with you directly (Shared with me → open).

Expected Outcome

" - Text Editor - OpenCloud".

Actual Outcome

"1d1ce624-…$…!… - Text Editor - OpenCloud"; screen readers announce the id.
