feat: Add optional cert issuer and TLS settings

[ds-jkreutzfeld]

Description

This PR enhances the Umbrella Chart with TLS configuration support, making it easier to deploy a secure Tractus-X environment with HTTPS.

1. Added Comprehensive TLS Configuration Example

• Created a dedicated file that provides ready-to-use TLS configurations for all components values-tls.yaml
• Configured ACME issuer integration with cert-manager for automated certificate management
• Set up proper TLS host configurations across all components

2. Enhanced TLS Documentation

• Expanded the TLS setup documentation with instructions for both ACME and self-signed certificate workflows
• Added warnings about using domains with ACME issuers .test
• Provided clear examples of how to apply TLS configurations manually or using the new values file

3. Fixed Ingress and TLS Configuration Issues

• Corrected TLS configurations for various components
• Fixed domain name consistency (replaced incorrect sdfactory.tx.test.net with sdfactory.tx.test)

4. Improved Default Values

• Updated default values to make TLS configuration more intuitive
• Standardized TLS configurations across all components

Usage

Users can now enable TLS in two ways:

1. Use the provided TLS example file: helm upgrade --install umbrella charts/umbrella --namespace umbrella -f charts/umbrella/values-tls.yaml
2. Manually configure TLS by following the expanded documentation in docs/user/network/tls.md
