Migrate KeyCloak-SW360 Database Communication to Direct CouchDB Access

Overview

This PR migrates KeyCloak’s database communication from Thrift via the SW360 application to a direct CouchDB connection using library functions. This decouples KeyCloak from the SW360 application, allowing both to run independently and improving performance.

Changes

• Integrated CouchDB library functions for direct access in KeyCloak
• Reused existing Thrift-based data models (to be migrated later)
• Implemented and verified direct connectivity between KeyCloak and CouchDB
• Developed functional tests for read, write, import, and update operations
• Ensured KeyCloak can operate without the SW360 application running
• Updated documentation for new architecture and configuration

Test Cases (all completed)

• KeyCloak can read data from CouchDB via the new direct connection
• KeyCloak can write/update data in CouchDB via the new direct connection
• KeyCloak can perform import operations directly to CouchDB
• KeyCloak can perform update operations directly to CouchDB
• KeyCloak interacts with CouchDB successfully when the SW360 application is not running

Impact

• Simplifies communication architecture
• Improves performance and reliability
• Enables independent operation of KeyCloak and CouchDB

Closes #3405
