refactor(helm): Unified Naming Truncation and Bug Fixes (#8143)

* refactor(helm): add componentName helper for truncation

* fix(helm): unify ingress backend naming with truncation

* fix(helm): unify statefulset/deployment naming with truncation

* fix(helm): add missing labels to services for servicemonitor discovery

* chore(helm): secure secrets and add upgrade notes

* fix(helm): truncate context instead of suffix in componentName

* revert(docs): remove upgrade notes per feedback

* fix(helm): use componentName for COSI serviceAccountName

* helm: update master -ip to use component name for correct truncation

* helm: refactor masterServers helper to use truncated component names

* helm: update volume -ip to use component name and cleanup redundant printf

* helm: refine helpers with robustness check and updated docs
