Pull request overview

Adds an organization-level setting to control the default repository sort order on the organization repositories page when no explicit sort query parameter is provided.

Changes:

• Introduces an org setting (org.repo_default_sort) persisted in user_setting keyed by org ID.
• Reuses a shared template partial for repository sort options across repo list UIs and org settings UI.
• Extends integration coverage to verify persisted setting and default sort behavior on the org page.

The sort options are always rendered with star-based sort choices enabled (DisableStars hardcoded to false). Since the web context already exposes .DisableStars (from setting.Repository.DisableStars), this will incorrectly show star sort options even when stars are disabled site-wide. Pass the actual .DisableStars value so the options list matches the rest of the UI and the backend feature set.

Suggested change

	{{template "shared/repo/sort_options" dict "CurrentSort" .RepoDefaultSort "DisableStars" false "Kind" "select"}}
	{{template "shared/repo/sort_options" dict "CurrentSort" .RepoDefaultSort "DisableStars" .DisableStars "Kind" "select"}}

In the ctx.HasError() branch, RepoDefaultSort is reloaded from the saved org setting, which discards the value the user just submitted when some other field fails validation (or when repo_default_sort itself hits a binding error). Prefer populating ctx.Data["RepoDefaultSort"] from form.RepoDefaultSort when present, and only fall back to getOrgRepoDefaultSort when the form didn't provide a value.

Suggested change

	if repoDefaultSort, err := getOrgRepoDefaultSort(ctx, ctx.Org.Organization); err == nil {
	if form.RepoDefaultSort != nil {
	ctx.Data["RepoDefaultSort"] = *form.RepoDefaultSort
	} else if repoDefaultSort, err := getOrgRepoDefaultSort(ctx, ctx.Org.Organization); err == nil {

getOrgRepoDefaultSort is called on every org home/settings page view, but it uses user_model.GetUserSetting, which bypasses the user_setting cache (user_model.GetSetting does cache). Consider switching to user_model.GetSetting and treating util.ErrNotExist as an empty value to avoid an extra DB query per request.
