Refactor plugins and trustkit to use shared components

[cybermaggedon]

Summary

• Extract shared QueryWorkbench component, reducing SPARQL/GraphQL workbenches from ~450 lines each to ~150 lines
• Refactor all 10 plugin packages to use shared Button, Input, Select components instead of raw inline-styled HTML
• Extend Button props (title, onMouseEnter, onMouseLeave) and Input props (onFocus, onBlur) to support plugin use cases
• Fix Section component theme scope bugs in game-theory and risk plugins
• Net reduction of 686 lines across 22 files

Test plan

• Verify SPARQL and GraphQL workbenches function correctly
• Verify ConfigEditor and SearchInput work as before
• Check button styling consistency across plugins
