This task tracks the TLS Profile consistency work for the Installer component as part of Epic ACM-26882.

Parent Epic: ACM-26882 - [ACM] Central TLS Profile consistency

Action Required:

Refactor the component to dynamically inherit its TLS settings from the designated global configuration source, rather than managing them locally.

Key Requirements:
- Ensure the component uses the correct TLS version and cipher suites for PQC readiness
- PQC-resilient algorithms will be available only in TLS 1.3+
- Obtain TLS configuration from one of the three central sources:
* API Server configuration (default for most components)
* Kubelet configuration (for components running on nodes)
* Ingress configuration (for components serving ingress traffic)
- Ensure the component pulls TLS configuration from the appropriate knob that customers can adjust
- Support custom TLS profiles (not just Old, Intermediate, Modern defaults)

This is a release blocker for OpenShift 4.22

Acceptance Criteria:
- [ ] All local or hardcoded TLS configurations (protocols, ciphers, curves) removed from codebase and deployment scripts
- [ ] Component successfully fetches and applies TLS policy from central configuration source
- [ ] Security re-scan using tls-scanner confirms endpoint compliance with global TLS policy
- [ ] Service remains stable, functional, and accessible after changes
- [ ] Component explicitly respects all TLS profile settings (does not rely on Go defaults)
- [ ] Functional testing confirms component accepts only permitted TLS profile settings (including custom TLS profiles)
- [ ] Component is PQC-ready by properly adhering to all aspects of the configured TLS profile
