fix: combine filter prefix/suffix with gap text for associate lookup

When matching solver results against associates, now tries:
- gap text alone ("oe")
- prefix + gap ("joe" if prefix="j")
- gap + suffix
- prefix + gap + suffix

Composite matches (prefix+gap) get a +3 score boost since the
surrounding context confirms the match. Deduplicates by person_id,
keeping the highest-scoring match.
