fix: apply post-renderer to output-dir-template output (#2531) 
* fix: apply post-renderer to output-dir-template output

When --output-dir and --post-renderer are both passed to helm template,
Helm writes pre-post-renderer content to files and sends post-renderer
output to stdout. This workaround strips --output-dir from helm flags,
captures the post-renderer-processed stdout, and writes it to the output
directory.

Fixes #2515

Signed-off-by: yxxhero <aiopsclub@163.com>

* test: add integration test for issue-2515 (post-renderer with output-dir-template)

Verifies that --post-renderer output is written to files when
--output-dir-template is set, instead of pre-renderer content.

* fix: address review comments - correct HasPrefix args, fix output dir structure, fix test mock init
