feat(plsql): CUI strict search + country filter for ANAF

PL/SQL cauta_partener_dupa_cod_fiscal gains p_strict_search param:
- strict (=1): search only exact CUI form (ANAF-determined)
- dual (NULL): search all forms (existing anti-dedup behavior)
Skip denomination fallback when strict to force new partner creation.

Python: country filter excludes foreign companies from ANAF batch,
anaf_strict flag threaded sync→import→PL/SQL, normalize RO-space
in cod_fiscal_adjusted comparison to eliminate false positives.
