fix(deploy): address final review — sensitiveKeys snapshot, dirty scrubbing, transition race, refetch invalidations

- Issue 1: add List<String> sensitiveKeys as 4th field to DeploymentConfigSnapshot; populate
  from agentConfig.getSensitiveKeys() in DeploymentExecutor; handleRestore hydrates from
  snap.sensitiveKeys directly; Deployment type in apps.ts gains sensitiveKeys field
- Issue 2: after createApp succeeds, refetchQueries(['apps', envSlug]) before navigate so the
  new app is in cache before the router renders the deployed view (eliminates transient Save-
  disabled flash)
- Issue 3: useDeploymentPageState useEffect now uses prevServerStateRef to detect local edits;
  background refetches only overwrite form when no local changes are present
- Issue 5: handleRedeploy invalidates dirty-state + versions queries after createDeployment
  resolves; handleSave invalidates dirty-state after staged save
- Issue 10: DirtyStateCalculator strips volatile agentConfig keys (version, updatedAt, updatedBy,
  environment, application) before JSON comparison via scrubAgentConfig(); adds
  versionBumpDoesNotMarkDirty test
