feat(ci): enforce type safety with ESLint errors and pre-commit validation

- Change @typescript-eslint/no-explicit-any from warn to error to block builds with any types
- Add type-safety-check script for automated pre-commit validation
- Implement comprehensive pre-commit checks including ESLint, TypeScript compilation, and any type scanning
- Include database migration status verification in pre-commit process
- Provide colored output and clear guidance for type safety issues

This ensures type safety is enforced at the CI level and prevents regression of any type usage.
