fix(plsql): encoding-safe strip_diacritics + localitate match in address lookup

TRANSLATE with UTF-8 literals was silently corrupted when compiled via
Windows sqlplus (ĂăÂâÎî→����, ȘșȚț→????). Replaced with REPLACE/UNISTR
for comma-below→cedilla normalization + CONVERT US7ASCII. Also applied
strip_diacritics to localitate/judet in TIER 1 lookup and locality search
(was only on strada), fixing 'FĂLTICENI' vs 'FALTICENI' BINARY mismatch.
