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

* fix: address code review findings for deploy template

Code review fixes:
- CRITICAL: Update test schema to use `autoFix` instead of old `validate` parameter
- WARNING: Add `AppliedFix` and `AutofixResultData` interfaces for type safety
- WARNING: Add `autoFixStatus` field to response (success/failed/skipped)
- WARNING: Report auto-fix failure in response message

Changes:
- tests/unit/mcp/handlers-deploy-template.test.ts: Fixed schema and test cases
- src/mcp/handlers-n8n-manager.ts: Added type definitions, autoFixStatus tracking
- src/mcp/tool-docs/workflow_management/n8n-deploy-template.ts: Updated docs
