Bugs Fixed

1. pkg/models/models.go:184 - Fixed typo in ForeignKeyConstraint constant from "foreign_Key" to "foreign_key"
  2. pkg/readers/drawdb/reader.go:62-68 - Fixed ReadSchema() to properly detect schema name from tables instead of hardcoding "default"
  3. pkg/writers/dbml/writer.go:128 - Changed primary key attribute from "primary key" to DBML standard "pk"
  4. pkg/writers/dbml/writer.go:208-221 - Fixed foreign key reference format to use "table.column" syntax for single columns instead of "table.(column)"
