revert(home): bring back the pre-wrapped layout after an upload

The analysis bar that replaced the upload hero reads "another file to
analyze it." on its button — the fileAnother string is the tail of a
sentence, not a label — and pushes the results down behind a band of empty
space. Restore what the page did before: the hero and the drop zone stay
put, and dropping in another export replaces the analysis.

The persisted analysis is untouched; it survives navigation and the payment
redirect exactly as before.
