fix(mcp): default available_on_public_internet to true

Fixes breaking change where new MCP servers were private by default,
causing k8s/cross-cluster deployments to have their servers silently
stripped by IP filtering.

Changes all defaults to true across:
- litellm/proxy/_types.py (3 Pydantic models)
- litellm/types/mcp_server/mcp_server_manager.py (MCPServer class)
- litellm/proxy/schema.prisma + schema.prisma + litellm-proxy-extras schema
- mcp_server_manager.py YAML + DB loading fallbacks
- UI MCPPermissionManagement.tsx form defaults

See migration script in https://github.com/BerriAI/litellm/pull/22331 for
existing deployments that need to flip existing servers back to public.
