Version-specific actions, folder picker search, and copyable asset IDs

This release adds version-specific preview, download, and sharing actions, folder search in the folder picker, and a copyable asset ID in the sidebar.

Every asset version now has its own set of actions. Open a preview of any version, download the original file, or copy a public URL for image and video versions to share it elsewhere.

The folder picker now includes a search input, so finding a target folder in a large library no longer means expanding the tree by hand.

The Metadata panel in the single-asset sidebar now shows the asset ID with a copy button, so you can grab it for API calls, support requests, and debugging without digging through the network tab.

• Toasts no longer appear behind the panel separator or behind dialogs.
• The sidebar panel toggle no longer shifts position when you open and close the panel or select an asset, and its tooltip is no longer hidden behind the asset preview.
• Fixed a case where long folder titles and paths could collide with the Select button when browsing folders.
