### What problem does this PR solve?
This commit fixes an Undefined Behavior Sanitizer error triggered when
printing PUniqueId directly to an ostream. Among the three types of unique IDs,
`UniqueId`, `PUniqueId` (protobuf), and `TUniqueId` (thrift), only `UniqueId`
has an overloaded `operator<<`.
Attempting to stream the other two types leads to undefined behavior, making
the current approach error-prone.
Introduces a unified `print_id()` function for safely printing all unique ID
types (UniqueId, PUniqueId, TUniqueId). It is recommended to use `print_id()`
instead of streaming directly.
