Multiple license assigned ( WITH / OR ) operator

When an SBOM contains a license expression using the SPDX `WITH` operator
(e.g. `Apache-2.0 WITH LLVM-exception`), grant fails to look it up and logs:

` linux-raw-sys 0.12.1 Apache-2.0 OR Apache-2.0 WITH LLVM-exception OR MIT Unknown `

Grant logs `ERROR unable to get license by ID: Apache-2.0 WITH LLVM-exception`
on every affected component and treats the expression as unresolvable.

No files or tests are named. Start by tracing the SBOM license lookup that logs `unable to get license by ID`, using `Apache-2.0 WITH LLVM-exception` as the reproducer; done means SPDX expressions containing `WITH` resolve without the repeated error and affected components receive the correct license handling.
