* fix(helm): use componentName for all service names to fix truncation mismatch (#8610)
PR #8143 updated statefulsets and deployments to use the componentName
helper (which truncates the fullname before appending the suffix), but
left service definitions using the old `printf + trunc 63` pattern.
When release names are long enough, these two strategies produce
different names, causing DNS resolution failures (e.g., S3 cannot
find the filer-client service and falls back to localhost:8888).
Unify all service name definitions and cluster address helpers to use
the componentName helper consistently.
* refactor(helm): simplify cluster address helpers with ternary
* test(helm): add regression test for service name truncation with long release names
Renders the chart with a >63-char fullname in both normal and all-in-one
modes, then asserts that Service metadata.name values match the hostnames
produced by cluster.masterAddress, cluster.filerAddress, and the S3
deployment's -filer= argument. Prevents future truncation/DNS mismatch
regressions like #8610.
