Validate Dag and task IDs in the Java SDK
---
### Why
Java SDK currently accepts any string as Dag/task ID. Python SDK already
validates this with `validate_key` (max 250 chars, only letters, digits, `-`,
`.`, `_`), and ts-sdk added the same check in #69400.
### What
Adds the same validation to the Java SDK, so invalid IDs fail early at
registration.
