Add Official information page (EN/MK/SI) + fill real bank details

New legal/registration reference page at /{lang}/legal/ with the official
details: legal name, registered office, registration number (4128133000),
tax number (44932448), VAT status, SKIS activity, registration date, bank
(NLB d.d.), IBAN SI56 0284 3026 6115 703, SWIFT LJBASI2X, representative,
and contact. New css/pages/_legal.css. Linked as "Official information" in
the footer legal bar on all pages.

Also fills the Support page's bank-transfer card with the same real IBAN/
bank/SWIFT (placeholders removed). SEO block + hreflang + sitemap (210
pages) regenerated.

MK/SI labels AI-drafted -> native review. SWIFT LJBASI2X is inferred from
the IBAN bank code (02 = NLB) -> please double-check.
