Quality-of-life improvements for tables (pagination, CSV filenames)

[KevinPayravi]

Three quality-of-life improvements for our dashboard pages that have tbles:

• Pagination now allows you to jump between pages (via multiple buttons or number dropdown).

• Table exports to CSV now have more detailed filenames.
  • Before, all exports were named website_events.csv
  • Now, named like Institution_Exhibition-views_2025-07_2026-07.csv
• Add exhibition and source set names to exports.

Summary by CodeRabbit

• New Features

  • Added numbered pagination with ellipses, Previous/Next controls, and direct page navigation.
  • Curated-content CSV exports now include exhibition or primary source set information.
  • CSV downloads now use descriptive filenames based on the report, hub, contributors, and date range.

• Bug Fixes

  • Curated membership data is now retrieved consistently across displayed results and full exports.

• Documentation

  • Updated API documentation to describe curated membership retrieval, pagination, and CSV filenames.

📝 Walkthrough

Walkthrough

The dashboard now retrieves curated memberships by institution, includes them in curated event exports, provides expanded pagination controls, and assigns descriptive filenames to CSV downloads.

Changes

Analytics exports and navigation

Layer / File(s)	Summary
Institution-scoped curated memberships app/lib/dpla_api_response_builder.rb, spec/lib/dpla_api_response_builder_spec.rb	Curated membership lookup now uses bounded institution-scoped pagination with provider and contributor filters. Tests cover aggregation, request limits, and failure handling.
Curated event export integration app/lib/website_events.rb, app/lib/website_events_presenter.rb, spec/lib/website_events_presenter_spec.rb, spec/rails_helper.rb, README.md, app/helpers/curated_content_helper.rb	Curated event tables and CSV exports now include exhibition or primary source set memberships. Lookup uses hub and contributor metadata.
Condensed pagination controls app/helpers/pagination_helper.rb, app/views/shared/_pagination.html.erb, app/assets/stylesheets/dashboard.css, spec/helpers/pagination_helper_spec.rb	Pagination now provides numbered links, ellipses, clamped navigation, and a page-jump form that preserves query parameters.
Generated CSV filenames app/helpers/csv_filename_helper.rb, app/controllers/contributors_controller.rb, app/controllers/events_controller.rb, app/controllers/search_terms_controller.rb, spec/helpers/csv_filename_helper_spec.rb	CSV downloads now use sanitized filenames built from labels, hubs, contributors, and date ranges.

In `@app/lib/dpla_api_response_builder.rb`:
- Around line 111-126: The curated memberships pagination in
DplaApiResponseBuilder must discard partial results when any page request is
unsuccessful. Update the non-200 response handling in the pagination loop to log
the failure and return an empty hash immediately, and ensure the rescue path
also returns `{}` rather than the accumulated result.

In `@app/views/shared/_pagination.html.erb`:
- Around line 35-37: Update the page input and label in the pagination view so
label_tag :page references a matching unique input id; remove the id: nil
override or assign the corresponding id explicitly while preserving the existing
number-field attributes.

In `@README.md`:
- Line 96: Update the README description of
DplaApiResponseBuilder#curated_memberships to document its bounded pagination:
it may request up to five pages of 500 items and stops once all items are
retrieved. Replace the claim that it always makes one request regardless of
table size, while preserving the explanation of why per-institution fetching
benefits CSV exports.
