Refactor FinalizeDocumentJob config to use WorkerOptions

Replaces JobOptions and PDFBurnerParams with a new WorkerOptions class that encapsulates all job configuration, including PDF burning parameters as a nested record. Updates service registration and job constructor to use IOptions<WorkerOptions>. Removes obsolete configuration classes and centralizes options management for improved maintainability.
