* Auto-enable DNS rebinding protection for localhost servers
When a FastMCP server is created with host="127.0.0.1" or "localhost"
and no explicit transport_security is provided, automatically enable
DNS rebinding protection. Both 127.0.0.1 and localhost are allowed
as valid hosts/origins since clients may use either to connect.
* Add tests for auto DNS rebinding protection on localhost
Tests verify that:
- Protection auto-enables for host=127.0.0.1
- Protection auto-enables for host=localhost
- Both 127.0.0.1 and localhost are in allowed hosts/origins
- Protection does NOT auto-enable for other hosts (e.g., 0.0.0.0)
- Explicit transport_security settings are not overridden
* Add IPv6 localhost (::1) support for DNS rebinding protection
Extend auto-enable DNS rebinding protection to also cover IPv6
localhost. When host="::1", protection is now auto-enabled with
appropriate allowed hosts ([::1]:*) and origins (http://[::1] :*).
* Fix import ordering in test file
