Plan 03 Summary: Sources Index Pagination UX Upgrade

What Was Built

Replaced the manual prev/next pagination on the sources index with the shared pagination partial from Plan 01. The sources controller now exposes the full paginator result with total_count/total_pages, enabling page numbers and jump-to-page navigation.

Tasks Completed

1. Update SourcesController to expose @paginator -- Assigned @paginator = paginate(...) result, kept @sources = @paginator.records for backward compat. Removed @page, @has_next_page, @has_previous_page.
2. Replace sources index pagination with shared partial -- Removed ~25 lines of manual pagination markup, replaced with single render "source_monitor/shared/pagination" call preserving search params and Turbo Frame targeting.
3. Update sources controller tests -- Added tests for page numbers rendering, jump-to-page with search params preservation.
4. Clean up unused pagination code -- Verified no leftover references to removed instance variables.
