facebook: Page details — categories added, hours and Messenger FAQ refused by Meta

Second Facebook task of the day. Page settings changed by hand in the operator's
Chrome; every edit read back from a channel other than the one that made it,
because Meta's toasts have lied here before (2026-10-08: "A modositas nincs
mentve" arrived with a partial save).

- Contact (B1) was ALREADY SET, by the operator, before this run: Graph reads
  emails ["info@felhom.eu"] and phone "+36702378499". Verified, not typed.
- Place (B2) already city-only Budapest, as the operator chose. Service area
  REFUSED: Facebook offers the field but its picker has no "Magyarorszag",
  only cities. Control: "Szeged" returns Szeged. Left unset rather than
  narrowed to Budapest, which would shrink a coverage claim nobody authorised.
- Categories (B3) DONE: Informatikai vallalat (kept first, the only one shown)
  + Internetes ceg + Szoftverceg. Facebook's Hungarian list has no IT-support,
  IT-consulting or cloud category; eleven terms searched, and the one true
  match is a repair counter, which the fences rule out.
- Hours (B4) CANNOT be set and need not be: Facebook requires a street address
  first, which the fences forbid. Measured on the rendered page with controls
  present -- Zarva 0, Nyitva 0 while Budapest 1, Informatikai vallalat 1. The
  Page will never show "Zarva".
- Messenger FAQ (B5) REFUSED -> R-920: the automation does not exist for this
  Page. Catalogue holds exactly three templates; search "kerdes" returns none
  while the control "uzenet" returns two. COPY.md section 5 is written anyway,
  questions verbatim from gyik.html and answers condensed from each question's
  own answer, and waits like section 2 does (R-917).
- Link preview correct in both languages, re-scraped once each; only the
  expected fb:app_id warning, deliberately not fixed. Both report HTTP 206
  where a plain curl gets 200 -- Facebook's scraper, preview complete.

fb_probe.py read now also reports emails, phone, category_list, location,
single_line_address and hours, ONE FIELD PER CALL: a batched fields= list fails
whole when any member is unreadable, which would let one refused field hide the
other five. Refusals are logged verbatim and never retried; "null" and "not
returned" are logged apart. hours is never returned by Graph, which is why B4's
read-back had to come from the rendered page.

Also corrects the "Business & legal" header, which read 12 rows (P2 5) over a
section holding 11 (P2 4); with R-920 it is 12 (P2 4, P3 1, P4 7). Only the
section this commit edits -- the other drifting headers belong to a session
that owns the register.

No post, no invite, no money, no app or portfolio change, website unchanged.
