A real ebook doesn't have headers and footers or page numbers from a document like a PDF has. There is no sensible way know what size the page is (and absolutely not in advance), so headers and footers inherently don't work.
In theory ebooks could have been designed to support this, but mobi/ azw/KF7, azw3/KF8, KFX, LRF, PDB, OEBPS, epub2 etc don't support it.
PDF does, but it's electronic, not an ebook.
The epub3 fixed layout might, as would Kindle Print Replica, but those also are not true ebook schemes as fixed size page thus a large tablet or laptop or monitor is needed. They are schemes to replicate PDF. One of the Kindle Print replica formats is actually PDF in an Amazon DRM wrapper
