Fix sidebar scroll and footer display (#1152)

st0012 · web-flow · commit 6abf59675f0b · 2024-08-12T15:21:28.000+01:00
* Set nav's bottom to make it scrollable again

* Improve layout and navigation scroll behavior

- Ensured the footer is part of the `nav` and sticks to the bottom by default,
appearing at the bottom of the scroll when content overflows.
- Applied flexbox layout to `nav` and `main` to manage space distribution.
