Update Dockerfile and refactor BIGINT handling in database adapters

- Added bcmath extension to Dockerfile for improved numeric handling.
- Changed return type of getLimitForBigInt method to string across Adapter, Mongo, Pool, and SQL classes.
- Updated maxBigIntLength parameter in Attribute class to string for consistency in validation logic.
- Enhanced validation logic to use bccomp for BIGINT size comparisons.
