Fix schema name generation for branch names with forward slashes

- Update sed regex from 's/-/_/g' to 's/[-\/]/_/g' to handle both hyphens and forward slashes
- Fixes CI failures when branch names contain '/' characters like 'devin/ELE-4833-1753733759'
- Ensures valid database schema names are generated for all branch naming patterns
