chore(brand): drop LUX_ env-var prefixes (LUX_PATH, LUX_KMS_*, LUX_CGO, LUX_PRIVATE_KEY, LUX_AUTOMINE_*)

- scripts/* + .github/actions/* + .github/workflows/*: LUX_PATH ->
  NODE_PATH, LUX_VERSION -> NODE_VERSION.
- Dockerfile: LUX_CGO -> CGO_ENABLED (matches Go convention).
- staking/kms.go: LUX_KMS_ENDPOINT/PATH/TOKEN -> KMS_ENDPOINT/PATH/TOKEN.
- deploy-subnets.sh: LUX_PRIVATE_KEY -> PRIVATE_KEY.
- config/config.go: drop LUX_AUTOMINE_CCHAIN_GENESIS_PATH env override;
  downstream networks ship their own platform-genesis bundle instead.
