chore(cleanup): curățare masivă site Romfast — 29 ștergeri, design unitar, 404 custom

Faza A: șterge 29 fișiere orfane/duplicate (placeholder-e roa/2-5, module abandonate,
chatbot-uri experimentale, politica root duplicat, stub romfastsuport/index.html)

Faza C: design unitar pe 25 pagini rămase
- Navbar duplicate fix (mobile-class leaked în desktop nav)
- Hub aplicatii-erp.html: 6 carduri 2x3 simetric + card ROA AUTO nou
- Footer flex layout + copy "Ghid instalare ROA Client" (înlocuiește "Descarcă")
- Fonts normalizate la Inter:wght@300;400;500;600;700;800 (1 variant unic)
- href-uri interne corectate: politica → menu/politica, aplicatii → aplicatii-erp

Faza D: sitemap.xml regenerat (24 URL-uri valide, lastmod 2026-04-28),
robots.txt + Sitemap: directive

Faza F: 404.html custom (navbar + 6 recovery links + buton primar),
ErrorDocument 404 în .htaccess, sidebar roa-suport-tehnic (drop TeamViewer/Ammyy),
HORECA hotel section anchor #hotel + hero placeholder + sub-heading

verify-cleanup.sh: 17/17 chec-uri PASS (hrefs, og:url, canonical, sitemap, navbar,
footer flex, 404, hub carduri, sidebar, HORECA anchor)
