Export categories as ZIP

Builds a `kategorien.zip` for the authenticated user's selected company.
The ZIP contains `kategorien.csv` (semicolon-separated, Windows-1252,
depth-first in sort order with an `Ebene N` name column per tree depth)
plus one AVIF entry per category image, named `<fullHash>.avif`
(content-addressed, so shared hashes are deduplicated).
