[GH-29548] Avoid SELECT * in tokens_store.go (#29558)

* migrate Token Store GetByToken query to SQLBuilder

* explicitly enumerate columns, factor out query into constructor

* fix syntax error

* fix error handling

* spread args... instead of passing the array as a single param

* fix MySQL by casing columns correctly
