feat: n8n_deploy_template deploy-first with auto-fix (v2.27.2) (#457)

* feat: n8n_deploy_template deploy-first with auto-fix (v2.27.2)

Improved template deployment to deploy first, then automatically fix common
issues. This dramatically improves deployment success rates for templates
with expression format issues.

Key Changes:
- Deploy-first behavior: templates deployed before validation
- Auto-fix runs automatically after deployment (configurable via `autoFix`)
- Returns `fixesApplied` array showing all corrections made
- Fixed expression validator "nested expressions" false positive
- Fixed Zod schema missing `typeversion-upgrade` and `version-migration` fix types

Testing: 87% deployment success rate across 15 diverse templates
