Reformatted multiline function calls, object definitions, and queries for improved code readability and consistency. Adjusted imports and constraints where necessary.
- Removed explicit ENUM creation statements; rely on `sa.Enum` to auto-generate ENUM types during table creation.
- Cleaned up redundant `create_type=False` arguments to streamline definitions.
Completely rewrote migration 0004 to match current model definitions:
- Added issue_type ENUM (epic, story, task, bug)
- Fixed sprint_status ENUM to include in_review
- Fixed all table columns to match models exactly
- Fixed all indexes and constraints
