refactor: change status from string to integer type

- Change SignRequestStatus enum from string-backed to int-backed (0, 1, 2)
- Update database migration to use SMALLINT instead of VARCHAR(20)
- Update SignRequest entity to use int type for status property
- Reduces storage overhead and improves performance
- Integer values: 0=draft, 1=able_to_sign, 2=signed
