fix: user id 2 allowed uid range in dockerfiles and deployment files.

[a-klos]

This pull request updates the user ID used for running application containers and deployments from 65532 to 10001 across several services and infrastructure templates. This change helps ensure consistency and avoids warning that the user id is out of range (min/max ID)

Container user ID standardization:

• Updated the RUN adduser command in the Dockerfiles for admin-backend, document-extractor, mcp-server, and rag-backend services to use UID 10001 instead of 65532. [1] [2] [3] [4]

Kubernetes deployment configuration:

• Changed the runAsUser value in the securityContext of the deployment templates for admin-backend, backend, and extractor to 10001 instead of 65532. [1] [2] [3]
