feat: use inflekt@0.5.0 for shared name-matching and case helpers

- Bump inflekt to ^0.5.0 in graphql/query, graphql/codegen, graphile/graphile-settings
- Import fuzzyFindByName directly from inflekt in field-selector.ts and select.ts
- Delete local name-matching.ts (no longer needed)
- Replace local lcFirst/ucFirst/toCamelCase/toPascalCase/toScreamingSnake in
  codegen/utils.ts with re-exports from inflekt (single source of truth)
