hrw4u: Fix section placement for hookless rules in u4wrh

[zwoop]

Old header_rewrite rules without an explicit hook condition default to REMAP. When u4wrh converted these, the section opened inside the if-block instead of wrapping it. Also emit comments inline inside if-blocks instead of deferring them to after the section closes, and remove the now-unused deferred comment machinery. In the forward direction, indent block-level comments at the statement level.

Pull request overview

Fixes u4wrh conversion for legacy header_rewrite rules that omit an explicit hook by ensuring the section wraps the generated if-block (rather than being opened inside it), and adjusts comment emission/indentation to be inline and statement-aligned.

Changes:

• Relocate pre-section if blocks so the section header wraps them for hookless legacy rules.
• Emit comments inline within if blocks and remove deferred-comment buffering.
• Update/generate golden test fixtures for the new formatting and add an exception entry for the legacy no-hook case.
