fix(helm): trim whitespace before s3 TLS args to prevent command breakage (#8614)

* fix(helm): trim whitespace before s3 TLS args to prevent command breakage (#8613)

When global.enableSecurity is enabled, the `{{ include }}` call for
s3 TLS args lacked the leading dash (`{{-`), producing an extra blank
line in the rendered shell command. This broke shell continuation and
caused the filer (and s3/all-in-one) to crash because arguments after
the blank line were silently dropped.

* ci(helm): assert no blank lines in security+S3 command blocks

Renders the chart with global.enableSecurity=true and S3 enabled for
normal mode (filer + s3 deployments) and all-in-one mode, then parses
every /bin/sh -ec command block and fails if any contains blank lines.

This catches the whitespace regression from #8613 where a missing {{-
dash on the seaweedfs.s3.tlsArgs include produced a blank line that
broke shell continuation.

* ci(helm): enable S3 in all-in-one security render test

The s3.tlsArgs include is gated by allInOne.s3.enabled, so without
this flag the all-in-one command block wasn't actually exercising the
TLS args path.
