fix(memory): coerce null confidence when ranking search results (#4076)
search_memory_facts sorted matches by fact.get("confidence", 0), which
returns None for a fact whose confidence key is explicitly null, crashing
the sort comparison. Use _coerce_source_confidence so null/malformed
confidence values are normalized and clamped before ranking.
