Dashboard Page

**Problem statement**
Users doesn't have a page where they they will be directed after login which will be home to all necessary resources that they need
**Solution**
Users should have a page that has all the links and resource that they need to access.

**Additional context**
- the dashboard should suite both `individual` and `organisation` users.
- Dashboard should have an area where feeds will be displayed: users should be able to `click on specific posts`, `comment` and `react to posts`
- there should be a `side bar` which should contain various navigation links.
- `profile link` and `notification` should be at the top of the page
- users trying to access the Dashboard without login should be redirected to `register page`

No files, tests, or entry points are identified in the issue, so first locate the existing login flow and frontend page structure. Review how individual and organisation users are represented, then define the dashboard's navigation, feed interactions, profile and notification links, and unauthenticated redirect. Done means both user types can reach the dashboard and the listed interactions and access rule work.
