fix: add missing crystallizes column to SELECT queries and remove duplicate

- Remove duplicate crystallizes column from schema.go
- Add crystallizes to SELECT in transaction.go SearchIssues
- Add crystallizes to SELECT in ready.go GetReadyWork and GetNewlyUnblockedByClose
- Add crystallizes to SELECT in labels.go GetIssuesByLabel
- Add missing placeholder in issues.go INSERT VALUES
- Update migrations_test.go schema to include crystallizes column

Fixes test failures caused by schema/query column count mismatches.
