Stage 4: Rails 5.2 -> 6.1 on Ruby 2.7.2

- routing-filter 0.6.3 -> 0.7.0 (Rails 6.1 compatibility)
- RSS named routes rss_xml/rss_rdf added
- RouteWithParams workarounds: will_paginate_patch, content_path shim, safe_path helper
- Paperclip removed, replaced with FileAttachment concern (preserves URL scheme)
- Assets resource moved to /admin/assets (Sprockets middleware conflict)
- ApplicationRecord base class added, all models migrated
- Strong parameters added to Assets, Occurrences, Events, MenuItems controllers
- update_attributes -> update throughout
- render :nothing -> head :ok/:not_found throughout
- language_selector rewritten (removes :overwrite_params)
- Environment files updated for Rails 6.1 (eager_load, public_file_server, ActionMailer)
- Arel::Visitors::DepthFirst and Integer/Float duration patches removed from test_helper
- AssetsController tests added (10 tests covering upload, variants, destroy, auth)
- ImageMagick geometry: 460x250! for headline crop (not # which is invalid in IM6)
