Fix Cypher syntax in seed.py: use double quotes consistently

Fixed quote escaping issues that caused Cypher syntax errors. Changed all
string literals in generated Cypher to use double quotes instead of escaped
single quotes.

Fixes:
- AnalysisTask properties: proper list syntax with double-quoted strings
- CanonicalConcept/DataProduct/SurveyProcess: double-quoted names
- QualityAttribute: double-quoted properties
- REQUIRES edges: double-quoted string properties with proper escaping

Successfully tested: seeded 5 AnalysisTasks, 5 QualityAttributes, 5 REQUIRES
edges, 6 CanonicalConcepts, 4 DataProducts, 6 SurveyProcesses.
