fix: resolve undefined variable refs in billing retry paths (#2335)

Five undefined variable references across three cloud modules caused
billing retry paths to silently fail:

- digitalocean: doToken, doDropletId, doServerIp → _state.token/dropletId/serverIp
- gcp: gcpProject → _state.project
- aws: instanceName → _state.instanceName

These caused checkAccountStatus() and checkBillingEnabled() to always
return early, and billing retry saves to use wrong/undefined values.
