chore: clean up templates

Summary

This MR implements a comprehensive resources page to replace the navbar dropdown, fixes yarr_scans pagination issues, and includes several template improvements from previous work. It is a bit absurd that toppage ended up being a catch-all which made the logic a bit confusing.

Key Changes

Resources Page Implementation

• Created dedicated /resources page with organized sections using Bootstrap cards and list groups
• Organized content into 6 main sections: Communication, Tracking Spreadsheets, Module Assembly & QC Procedures, Software Tools, Troubleshooting, and Data Reporting
• Content derived from https://indico.cern.ch/event/1393709/contributions/6705401/attachments/3142152/5577467/2025.09.24.ModuleDocumentation.pdf (@fpablo's slides)

Bug Fixes

• Fixed yarr_scans pagination - now uses 'page' parameter with 1-based indexing (consistent with other tables)
• Fixed total count display - yarr_scans now shows correct total results instead of current page count only

Template Refactoring (from previous work)

• Extracted assembly module (685 lines) from monolithic toppage.py, reducing it by 40%
• Created unified pagination widget with First/Last buttons and dropdown ellipsis for page ranges
• Standardized pagination variables across all tables (page, total_pages, total_count, etc.)
• Added breadcrumb widget for consistent navigation
• Consolidated CSS styling into shared template parts
• Fixed alternative ID search and radio button logic in component tables
