chore: remove unused axios dependency from ContentProcessorWeb

Remove axios ^1.13.5 from package.json as all HTTP calls use native
fetch via the apiClient.tsx wrapper. Also update documentation
references in .github/instructions/ files.

- Remove axios from package.json dependencies
- Update pnpm-lock.yaml (pnpm install)
- Update test-quality.instructions.md to remove axios references
- Update code-quality.instructions.md to remove axios from import example

Resolves #39065
