Lecturer page

## Summary
Prepare lecturer's profile page according to our figma design. Use dummy data instead of API integration.

## [Acceptance criteria](https://www.atlassian.com/work-management/project-management/acceptance-criteria)
- [x] lecturer page is added and has layout from figma design. Colors and typography doesn't have to match at this stage.
- [x] it uses dummy data with defined schema that is validated by zod (this is our API contract).
- [x] All components are functional and work but they use predefined data.

## Notes
important context

Review open pull request #149 first, then compare the lecturer profile page with the referenced Figma design. Check that the page uses the defined dummy-data schema validated by Zod and that its predefined-data components remain functional; done means the checked acceptance criteria are satisfied.
