fix(B-08,NEW-1): remove duplicate fulltext from SETUP_QUERIES; modern CREATE FULLTEXT INDEX syntax

B-08: globalSearch fulltext index existed in three places: FULLTEXT_INDEX_QUERY
(informational, never called), SETUP_QUERIES (8-type CALL syntax, externally
run), and loader.py setup_schema() (20-type authoritative version). Running
SETUP_QUERIES externally tried to create a conflicting narrower index,
producing silent DatabaseError: index globalSearch already exists.
Removed from SETUP_QUERIES. loader.py is the single source of truth.

NEW-1: FULLTEXT_INDEX_QUERY used deprecated CALL db.index.fulltext.createNodeIndex
removed in Neo4j 5.x and AuraDB Free. Replaced with modern DDL:
CREATE FULLTEXT INDEX globalSearch IF NOT EXISTS FOR (n:...) ON EACH [...]
