refactor: preserve URL search params during navigation

Introduce `useNavigateWithParams` to ensure that existing URL search
parameters are maintained when navigating between pages. This is
applied to the Article component, FileTree, and journal links to
prevent losing state (like session or player info) during client-side
navigation.

Also intercepts markdown anchor links in the Article component to use
client-side navigation.
