Fix editor footer spacing

[lekhanpro]

Summary

• move the full-height page shell to the home page wrapper
• let the video editor size to its own content instead of reserving an extra viewport before the footer
• keep the footer naturally pinned after the main content on short pages

Closes #509

Testing

• git diff --check

Note: full dependency-based checks were not run locally because this clone has no node_modules and the local disk has insufficient free space for a dependency install.
