feat: add reveal in file manager option to workspace collections menu

[datlechin]

Summary

• Adds a "Reveal in Finder" (macOS) / "Reveal in File Explorer" (Windows) / "Reveal in File Manager" (Linux) option to the collections dropdown menu in the Workspace Overview page

Description

This PR adds the ability to quickly reveal a collection's folder in the native file manager directly from the Workspace Overview collections list.

The implementation reuses existing infrastructure:

• Uses the existing showInFolder Redux action
• Uses the existing renderer:show-in-folder IPC handler which calls Electron's shell.showItemInFolder()
• Uses the existing getRevealInFolderLabel() utility for OS-specific labels

Changes

• Added IconFolder import from @tabler/icons
• Added showInFolder action import from Redux store
• Added getRevealInFolderLabel utility import for platform-specific labels
• Added handleShowInFolder handler function
• Added the menu item to the collection dropdown (between "Share" and "Remove")

Screenshots

The menu item appears in the collection card dropdown with the appropriate label based on the user's operating system.
