fix: sync config files and delegate yq lookups to localhost

[ch4r10t33r]

Summary

• Add automatic config file sync in deploy-nodes.yml before deployment to ensure remote hosts have up-to-date configuration
• Delegate all yq commands to localhost in roles and deploy-single-node.yml to fix "node not found" errors when remote config is stale
• Make data directory cleanup conditional in spin-node.sh to prevent sudo password prompts for local deployments

Changes

deploy-nodes.yml:

• Syncs validator-config.yaml, node key files, and essential genesis configs before deployment
• Syncs hash-sig-keys directory (for qlean nodes)

All client roles (zeam, ream, qlean, lantern, lighthouse, grandine, ethlambda):

• Added delegate_to: localhost to yq commands that read from validator-config.yaml
• Uses local genesis path for lookups ensuring authoritative configuration is used

deploy-single-node.yml:

• Delegated node existence check to localhost

spin-node.sh:

• Made rm -rf cleanup conditional on cleanData and dockerWithSudo flags

Test plan

• Run Ansible deployment with --node all and verify all nodes deploy successfully
• Verify config files are synced to remote hosts before deployment
• Test local deployment mode still works without sudo prompts
