Function repos_conf_section_is_disabled_with_apply_sources 

pub fn repos_conf_section_is_disabled_with_apply_sources(
    content: &str,
    section_name: &str,
) -> Result<bool, String>

What: Whether repos.conf has a matching [[repo]] that is disabled but still defines apply sources.

Inputs:

• content: Full repos.conf text.
• section_name: Pacman [repo] name (case-insensitive trim).

Output:

• Ok(true) when a row matches, has enabled = false, and repo_row_declares_apply_sources.
• Ok(false) when no such row exists.

Details:

• Used so the Repositories modal can re-enable a row after Apply removed it from pacman: pacman no longer shows the section as active from pacsea-repos.conf, but repos.conf still carries the recipe.

Errors

• Propagates load_resolve_repos_from_str failures.
