Add advanced reload and history clearing features

Introduces hard reload and fresh reload buttons to the UI, allowing users to reload pages while ignoring cache or with a cache-busting parameter. Refactors session and browser data clearing logic to handle multiple sessions and resets history JSON files. Adds per-section clear buttons for site and search history in settings, improving user control over stored data.
