[feat] Add ZIP download support for multiple assets

[viva-jinyi]

Summary

When downloading multiple selected assets, they are now bundled into a single ZIP file instead of downloading each file individually.

Changes

• Use client-zip library to generate ZIP files in the browser
• Use Promise.allSettled to include remaining files in ZIP even if some fail
• Automatically add numbers to duplicate filenames
• Notify users with toast messages based on download status
• Auto-generate filename with timestamp to prevent filename collisions

Modified Files

• src/platform/assets/composables/useMediaAssetActions.ts: Implement ZIP download logic
• src/locales/en/main.json: Add new i18n strings
• package.json: Add client-zip dependency
