clean_web_text used a hard-coded Romanian-only translation map, so Hungarian
(BALÁZS LORÁNT), German, Czech, Polish names passed through unchanged into
SQLite and Oracle ROA. Replace with unicodedata.normalize('NFKD') + combining
mark strip — covers RO/HU/DE/CZ/PL/FR/ES universally. Romanian cedilla legacy
forms (ş/ţ/Ş/Ţ) remain handled (NFKD decomposes to base + combining cedilla).
Stroke letters not decomposed by NFKD (ß, ł, đ, ø, æ, œ) covered via
_NFKD_OVERRIDES translation map.
sync_service._addr_match.norm migrated off the removed _DIACRITICS constant
to clean_web_text; address matching now also handles non-RO diacritics.
