TRUNK-5466: Add supportsVisits attribute to Location

[Akshat-coder2106]

Description

I have implemented the changes requested in TRUNK-5466 to support the "Visit Location" feature in the core domain model.

Changes:

1. Java Domain: Added private Boolean supportsVisits field to Location.java with Getter/Setter methods.
2. Database: Added a Liquibase changeset to create the supports_visits column in the location table (default: false).

Testing

• Ran mvn clean install -DskipTests to verify build.
• Ran mvn test -Dtest="Location*" to verify unit tests for the modified class.
• Verified that the Liquibase changeset is valid xml.
