HT-14: PDF-lépés eltávolítva — csak HTML render

Az ÁSZF saját 3.2. pontja "megismerhető, megjeleníthető és letölthető"
szöveget kér — ezt egy önálló (külső CSS/JS-függőség nélküli) HTML oldal
is teljesíti (böngészőből menthető/nyomtatható), külön PDF-render nélkül.

Ez NEM ugyanaz, mint a HRF-33/34 ajánlat-szerződés PDF-je — az egy
ténylegesen elfogadott, hash-elt clickwrap-példány, más indokkal; azt nem
érinti ez a változás.

Egyszerűsödött CI-környezet: WeasyPrint + natív libek (pango/cairo) törölve,
csak pandoc + python3 kell. A manifest "pdf" mezője megszűnt.

A rendereletHTML immár kicsi (nincs PDF), ezért a teljes dist/ kimenet
visszacommitolódik "manifest/" néven (nem csak a JSON) — a fogyasztók
ugyanazzal a git clone-nal a HTML-t is megkapják, nem csak a metaadatot.

+HTML only, no PDF: the ÁSZF's own 3.2. clause requires the text to be "megismerhető,
