Add admin CSV export for citation data (per-journal and all-journals)

[Copilot]

Admins have no way to extract citation data in bulk — citations are only surfaced per-article in the frontend widget. This adds a CSV export endpoint usable by journal managers and site admins.

Endpoint

GET /index.php/<journal>/citations/export

• Journal manager / site admin → exports all published articles with DOIs for the current journal
• Site admin only → append ?scope=all to export every enabled journal in one file

Export always fetches full citation lists (ignores the showList display setting) from all configured providers (Crossref, Scopus, EuropePMC).

CSV columns

Journal · Article DOI · Article Title · Article Year · Citation Source · Citation DOI · Citation Title · Citation Authors · Citation Journal · Citation Year · Citation Volume · Citation Issue · Citation Pages · Citation Type

UTF-8 with BOM for Excel compatibility.

Plugin UI

Two new action buttons in the Plugin Management page:

• Export Citations (CSV) — managers + site admins
• Export All Journals (CSV) — site admins only

Implementation notes

• export() added directly to CitationsHandler (same page, new op — no routing changes needed)
• Filename sanitized before injection into Content-Disposition header
• $settings['provider'] guarded with ?? '' to handle partially configured plugins
• Single getAllContextMap() call fetches all context names to avoid N+1 queries on the all-journals path

@copilot it looks like you pulled main immediately before the port to feature was implemented. Review all of the changes that went into #2 including reviewing any interface changes to 3.5. Make sure that you have implemented in a way that is compatible with 3.5 and fix the conflict with the new state of main.

Done. I merged main (which contains PR #2's OJS 3.5 port) into this branch and resolved the conflict in CitationsPlugin.php. The three OJS 3.5 breaking changes from PR #2 are now incorporated alongside the export feature:

• setPageHandler: uses $params[3] = new CitationsHandler() instead of define('HANDLER_CLASS', ...)
• getActions: removed the legacy import('lib.pkp.classes.linkAction.request.AjaxModal') call
• CitationsSettingsForm: uses PKP\notification\Notification::NOTIFICATION_TYPE_SUCCESS instead of PKPNotification::

@copilot Getting https://iopn.library.illinois.edu/journals/uijm/$$$call$$$/ci/export?scope=all and a 404 on export all and similar on export for journal when using the link in the UI. It might be relevant that we are rewriting urls in an .htaccess file:

<IfModule mod_rewrite.c>
   RewriteEngine on
   RewriteBase /journals/
   RewriteCond %{REQUEST_FILENAME} !-d
   RewriteCond %{REQUEST_FILENAME} !-f
   RewriteRule ^(.*)$ index.php/$1 [QSA,L]
</IfModule>
in an attempt (I believe) to get a cleaner looking url

Directly calling iopn.library.illinois.edu/journals/jams/citations/export produces a csv, but iopn.library.illinois.edu/journals/jams/citations/export?scope=all produces a 500 error with :

Fixed in the latest commit. Two issues were addressed:

1. $$$call$$$ URLs — getActions() runs inside a component handler context, so $router->url() was generating component-style URLs. Replaced with $request->getDispatcher()->url($request, Application::ROUTE_PAGE, ...) which always generates proper page-handler paths regardless of calling context.

2. 500 on ?scope=all — Application::getContextService() doesn't exist in OJS 3.5. Replaced getAllContextMap() with Repo::journal()->getCollector()->filterByEnabled(true)->getMany(), which is the correct 3.5 API.

@copilot do a complete review to make sure all work here is compatible with 3.5 and make sure that any fix is likewise. Getting new error on the get all journals call:

Repo::journal() doesn't exist in OJS 3.5 either — only Repo::submission() is available. Fixed by replacing with DAORegistry::getDAO('JournalDAO')->getAll(true), which iterates over enabled journals via the DAO layer that does exist in 3.5.

I also reviewed the rest of the handler: Repo::submission()->getCollector(), PKPApplication::SITE_CONTEXT_ID, Role::ROLE_ID_*, and PKP\notification\Notification::NOTIFICATION_TYPE_SUCCESS in the settings form are all confirmed valid 3.5 APIs.
