Always use hash for dashboard tabs

Previously the dashboard used a clean root URL for the 'apps' tab and hashes for other tabs. This change makes tab links and history entries consistently use a hash (e.g. #apps, #home) by always generating href as `#<id>` and pushing `#<section>` to history. Simplifies URL handling and ensures the Apps tab also reflects its hash in the address bar.
