Apply TLS profile settings to the metrics server via controller-runtime's TLSOpts.

File to modify:

• cmd/kueue/main.go

Implementation:

metricsServerOptions.TLSOpts = append(metricsServerOptions.TLSOpts, func(config *tls.Config) {
    config.MinVersion = tlsVersionFromConfig(cfg.Metrics.MinTLSVersion)
    config.CipherSuites = cipherSuitesFromConfig(cfg.Metrics.CipherSuites)
})

Acceptance Criteria:

• Metrics server respects minTLSVersion from configuration
• Metrics server respects cipherSuites from configuration
• Defaults to Intermediate profile when not specified
• TLS scanner confirms correct settings

Depends on: OCPKUEUE-451 (API fields)
