Merge UploadService, EditService, JobOrchestrationService, and
DownloadService into a single MediaService with a unified Job lifecycle
(READY → PROCESSING → SUCCEEDED/FAILED via JobState enum).
- Add MediaController (/api/v1/media) exposing compress, save, and clip
- Add JobController (/api/v1/job) for status polling and file download
- Move clip/thumbnail download into ClipController (/{id}/media, /{id}/thumbnail)
- Move stream saveSection/clip from StreamService into MediaService
- Simplify Job DTO: remove dual ClipOptions/files, add ProgressTracker and download file
- Refactor JobRegistryService.add() → generateJob() to co-locate creation and registration
- Wire FFmpeg out_time_ms progress parsing into StreamActionsService via CommandRunner
- Rename GET /api/v1/auth/user → GET /api/v1/user/me
- Delete DownloadController, MetadataController, UploadController
persistClip() had grown too large and handled multiple concerns.
This change moves the database save logic into saveClip(), making
persistClip() smaller and easier to refactor further.
The original clip creation method in ClipService handled many different services, like metadata handling, callback methods and more. Moving it to a more suitable location in the JobService allows it to easily access the Job object and update it upon failure.
Validation was happening in two places, in both EditService and in MetadataService doing different validations. This unifies them both into a singular method
