* fix: add n8n 1.121 availableInMCP and callerPolicy settings support (v2.26.4)
n8n 1.121 introduced a new workflow setting `availableInMCP` (boolean)
that controls whether a workflow is "Available in MCP". The sanitization
whitelist was missing this field, causing it to be silently stripped
during workflow updates.
Changes:
- Added `availableInMCP` to Zod schema in workflowSettingsSchema
- Added `availableInMCP` and `callerPolicy` to safeSettingsProperties whitelist
- Both settings are now preserved during workflow updates
- Settings can be toggled via updateSettings operation

* test: update tests for callerPolicy and availableInMCP whitelist changes
Updated 5 tests in n8n-validation.test.ts that expected callerPolicy
to be filtered out. Since callerPolicy and availableInMCP are now
whitelisted (n8n 1.121+), the tests now verify these settings are
preserved during workflow updates.
