Refactor RenderBumperPreviewCommandHandler to streamline background path resolution and rendering specification. Introduce helper methods for improved readability and maintainability. Update FindMissingEpisodesQueryHandler and RefreshShowEpisodesMetadataCommandHandler to encapsulate episode number resolution logic. Enhance CopyTemplateCommandHandler by modularizing junction copying and slot handling for better clarity. Improve FfmpegMediaProcessor by separating duration and stream parsing into dedicated methods. Refactor MediaClaimingBackgroundService to simplify idle waiting logic. Update GenreSeeder to modularize alias addition logic, enhancing code organization.
