feat: support SSR for OnyxSelect, OnyxNavButton, OnyxUserMenu and more components

[larsrickert]

Relates to #1521

Support SSR for OnyxSelect, OnyxNavButton, OnyxUserMenu and more components by:

• update to Vue 3.5
• replace custom createId() with Vue's new useId() which is SSR compatible
• a few other SSR fixes
• also fixes the missing JSDoc for properties (see Implement feedback from alpha testers - part 4 (nice to have) #1498)

Checklist

• The added / edited code has been documented with JSDoc
• A changeset is added with npx changeset add if your changes should be released as npm package (because they affect the library usage)

To fix the storybook build we need to update to storybook 8.3 beta but we need to wait for storybookjs/storybook#28760 to be released first, otherwise property controls are missing for booleans and enum/union types
