Add archived repository filters to global code search

[MaxWebZ]

The repository archived state is now indexed for code search and used in both supported search backends, so result counts, pagination, sorting, and language facets stay consistent with the selected filter.

A filter dropdown similar to the one on the repositories page has been added to the code search page.

Archiving or unarchiving a repository now also resets the code index status so the repository is fully reindexed and the archived state is reflected in search results.

Fixes #17824.

Pull request overview

This PR adds support for filtering code search results by repository archived state, ensuring the archived flag is indexed and queryable across both Bleve and Elasticsearch, and updates UI + reindex behavior so results/facets remain consistent with the selected filter.

Changes:

• Index archived state in code index documents and add an archived filter to both Bleve and Elasticsearch search queries.
• Add an “Archived” filter dropdown to the shared code search UI and propagate the selection into language facet links.
• Reset code indexer status and trigger a full reindex when archiving/unarchiving repositories (web settings + API).

shared/search/code/search.tmpl is included by repo and user/org code search pages, but those handlers (e.g. routers/web/repo/search.go, routers/web/user/code.go) do not set .ArchivedMode / .IsArchived. Using eq .ArchivedMode ... and .IsArchived.Value will cause template execution errors (nil/incompatible types) on those pages, and even if it doesn’t error, the archived radio state/filter won’t work there.

Consider initializing these values for all code-search pages (e.g. in common.PrepareCodeSearch), and ensure the user/org code search handler passes the parsed archived filter into code_indexer.PerformSearch. For repo-scoped search, it may be better to hide the archived filter entirely since the repo is already fixed.

One UI suggestion: Render in the dropdown this:

[x] Archived
[x] Not archived

It would be similar UX than the label filter in issue list, could either be actual checkboxes or just SVG checkmark like in the label filter. In the future, this could be extended to add more checkbox groups separated by a horizontal separator.

I agree, that would be closer to the existing Gitea UI patterns.
Done.

The original issue and related PR's participants (jpraet, lunny, silverwind, lafriks, delvh) are maintainers, they should know more details than me.

It's better to have a new notifier event like ArchiveRepository.

Suggested change

	case archivedModeInclude:
	return archivedModeInclude, optional.None[bool]()
	case "":
	return archivedModeInclude, optional.None[bool]()

[lunny]

Unarchived filter doesn't work.
