fix(mana-notify): resolve BullMQ circular import issue

Move queue name constants to separate file (queue-names.ts) to avoid
circular dependency between queue.module.ts and processor files.

The @Processor decorator evaluates at module load time, and importing
constants from queue.module.ts created a circular dependency that
resulted in undefined queue names.
