Website: add RPC API documentation with CI validation

[dannywillems]

Summary

• Add comprehensive RPC API documentation for the Mina Rust node's HTTP endpoints
• Create new api-and-data section and reorganize existing API documentation
• Add CI workflow to validate RPC endpoints against o1Labs node daily
• Add rustdoc comments to Rust RPC response structs with links from documentation

Changes

• New documentation: website/docs/developers/api-and-data/rpc-api.md with all RPC endpoints documented alphabetically
• CI workflow: .github/workflows/test-rpc-remote.yml runs daily and on PR/push to validate endpoints
• Curl scripts: 17 scripts in scripts/rpc-api/curl/ for endpoint examples
• Rust docs: Added rustdoc comments to RPC response structs in node/src/rpc/mod.rs
• Reorganization: Moved GraphQL and archive docs to api-and-data/ subdirectory
• Link fixes: Updated broken links after reorganization

Closes #1743

New mandatory CI jobs

The following jobs should be added as required status checks on develop and main branches:

Job Name	Workflow
Test Rust Node RPC Endpoints (ubuntu-latest)	test-rpc-remote.yml
Test Rust Node RPC Endpoints (macos-latest)	test-rpc-remote.yml

Commands to add branch protection rules

# Add required status checks for develop branch
gh api repos/o1-labs/mina-rust/branches/develop/protection \
  --method PUT \
  --field required_status_checks='{"strict":true,"contexts":["Test Rust Node RPC Endpoints (ubuntu-latest)","Test Rust Node RPC Endpoints (macos-latest)"]}' \
  --field enforce_admins=false \
  --field required_pull_request_reviews=null \
  --field restrictions=null

# Add required status checks for main branch
gh api repos/o1-labs/mina-rust/branches/main/protection \
  --method PUT \
  --field required_status_checks='{"strict":true,"contexts":["Test Rust Node RPC Endpoints (ubuntu-latest)","Test Rust Node RPC Endpoints (macos-latest)"]}' \
  --field enforce_admins=false \
  --field required_pull_request_reviews=null \
  --field restrictions=null

Note: To append these checks to existing branch protection rules (preserving current settings), use the GitHub web UI at:

• https://github.com/o1-labs/mina-rust/settings/branches
• Edit the branch protection rule for develop and main
• Under "Require status checks to pass before merging", add the new job names
