Description

An open received share now shows its real favorite state and tags in the folder actions, so a favorite share no longer offers "Add to favorites" and toggling it works as expected.

How Has This Been Tested?

• test environment: unit tests (Vitest), browser tests (Playwright) against a local OpenCloud
• test case 1: unit: the share root keeps the WebDAV favorite state and tags
• test case 2: browser: favorited folder share with a tag (desktop and Pixel 7), toggling from the folder actions, non-favorite share, single-file share and personal folders
