fix(web): correct Lambda handler class name and property ID format

Two independent functional breaks in the Java Web service:

1. template.yaml Handler referenced publicationmanager.PublicationEvaluationEventHandlerFunction, but the class is named PublicationEvaluationEventHandler (no 'Function' suffix). Every PublicationEvaluationCompleted delivery threw ClassNotFoundException, so property status was never updated to APPROVED/DECLINED.

2. Property.getId() built the id by joining the DynamoDB partition/sort keys (PROPERTY#country#city + street#number) and replacing '#' with '/', producing a 5-segment id like 'PROPERTY/usa/anytown/main-street/111'. Every consumer — the approvals state machine's DynamoDB lookups, and Web's own PublicationEvaluationEventHandler, which explicitly requires exactly 4 segments — expects the canonical 4-segment 'country/city/street/number' format used by every other language track. Rebuilt getId() directly from the raw address fields to match.

Verified: PublicationEvaluationEventHandlerTests and RequestApprovalFunctionTests (which exercise getId() indirectly) pass; sam validate --lint clean.
