fix: resolve all 5 failing integration tests

- Fix setup time test: expected 1 result not 2 (only 15min < 30min)
- Fix category test: 'ai' substring matches 2 templates due to LIKE pattern
- Fix templates without metadata: increase view count to avoid filter (>10)
- Fix metadata stats: use correct property names (withMetadata not totalWithMetadata)
- Fix pagination test: pass limit/offset as separate params not in filters object
