website: publish the closed-test legal set (R-813 narrowed)

Two new Hungarian pages, live on push: /adatkezeles (privacy notice) and
/feltetelek (what the free closed test is, and is not). Operator rulings of
2026-10-09: no company exists yet, so the operator is named as a PRIVATE
PERSON with no postal address and no phone; publish before the lawyer has
seen it, because the site was collecting data with no notice at all; the full
ASZF, the impresszum and the review wait for the company (R-802, R-809).

- All 18 pages carry the operator, info@felhom.eu and both links in the
  footer. Counted, not assumed: 18 pages found = 18 with both links = 18
  structurally valid. English footers say the legal texts are Hungarian.
- The contact form stopped claiming something untrue. The old consent said
  "az adatokat harmadik felnek nem adjuk ki" while Resend, Cloudflare and
  Google carry the message. Both languages replaced; the link opens in a new
  tab so a filled form is not lost.
- site_gates.py NO_TWIN gains the two pages ON PURPOSE, with the reason in a
  comment: an unreviewed English legal text would be worse than an honest
  pointer from the English footer.
- documentation/legal/{adatkezelesi-tajekoztato,feltetelek}-1.0.md are the
  text of record, DERIVED from the published HTML so they cannot drift. The
  drafts are kept and marked superseded for the closed test.

FOUR LOAD-BEARING CLAIMS WERE MEASURED, not copied from a vendor or a README:

  cookies      zero, and no local storage - checked in the browser WITH A
               POSITIVE CONTROL (a probe cookie WAS visible to the same
               method) after the tracker fired; no Set-Cookie on any response
  beacon       the exact Umami payload: site id, screen, language, title,
               url, referrer - no visitor identifier
  Cloudflare   DNS only: the public A record 37.191.56.193 is not a
               Cloudflare address, so site traffic cannot be proxied
  fsn1         Falkenstein, Germany (Hetzner's own location list)

Also measured: felhom-ep0-copy-gc.timer is installed and RAN SUCCESSFULLY
(2026-10-09 08:00, exit 0), so "deleted within 30 days" is true today where
on 2026-10-08 it was written but not switched on.

Three retentions are stated as having NO deadline, deliberately and with the
operator's word: website statistics, web server logs and contact messages
have no automatic deletion, and the pages say so instead of promising a date
nothing enforces. Every other period is enforced by configuration and cited.

No placeholder survived onto either page (0 of "[[", control: the draft still
has 36). The impresszum and the full ASZF are NOT published.

R-813 -> NARROWED. R-915 unblocked: the operator enters the two URLs in the
Meta app's Basic settings; the Live switch stays a separate decision.
R-917 and R-920 -> DEFERRED on the operator's (c): park, publish as posts
once posting starts.
