Metrics serviceName can exceed 63 naming limit

[guntiskarulis]

Which component:
Controller: 0.24.5
Helm chart: 2.14.1

Describe the bug
Metrics service name can exceed 63 character limit, because Helm template engine will include sealed-secrets.fullname to generate name and in this helper function it will truncates string to 63 characters, hoverver service name itself will add additional characters to the service name, i.e -metrics thus deployments will fail.

Using nameOverride and fullNameOverride will update selector labels, thus breaking controller deployment.

To Reproduce
Deploy sealed-secrets chart, with Release.Name close to 63 characters.

Expected behavior
Provide a way using Helm values to override metrics service name.

Version of Kubernetes:

• Output of kubectl version:

Client Version: v1.30.3
Server Version: v1.30.3

To me it sounds natural to truncate the fullname to something like 50 characters to make room for suffixes. What do you think?
