Adds the PlayList picture-processing lifecycle saga (correlated by PlayListId)
mirroring the track one, and generalizes the failure plumbing:
- Rename the track fault translator to ProcessingSlipFaultConsumer and use a
generic Workflow.SubjectId variable + ProcessKind; it now emits typed
Track{Picture,Audio}/PlayListPicture ProcessingFailed events for all slips
- PlayListProcessingStateMachine (+ EF-persisted PlayListProcessingState,
migration): starts on CreatePlayListResourcesEvent, finalizes on
PlayListPictureProcessed, and on failure marks the playlist Failed and
removes the orphaned final picture (PlayListProcessingFailedConsumer +
MarkPlayListAsFailedActivity)
- UpdatePlayListPictureActivity publishes PlayListPictureProcessed on success
- Picture slip carries SubjectId + PlayListPicture kind + fault subscription
Verified end-to-end in Docker (RabbitMQ + migrated Postgres): both saga
endpoints, the fault translator and cleanup consumers configure, and an
addressing cross-check confirms all 21 activity execute queues the builders
address exist (caught + fixed a kebab mismatch on mark-play-list-as-failed).
Build: 0 warnings, 0 errors.

On definitive failure of the picture or audio slip, the saga now reaches a
Failed state and recovers end-to-end:
- Picture/audio track slips carry TrackId + ProcessKind variables and a
subscription to a fault translator (TrackProcessingSlipFaultConsumer) that
turns RoutingSlipFaulted into a typed Track{Picture,Audio}ProcessingFailed
- The saga stores the final object keys from the start event and, on failure,
transitions to Failed and publishes TrackProcessingFailed
- TrackProcessingFailedConsumer runs a cleanup slip that removes the orphaned
final picture/audio copies and marks the track LifeCycleStatus=Failed
(MarkTrackAsFailedActivity) — the track stays as a visible, recoverable record
- Migration for the new saga columns
Verified: Worker boots against RabbitMQ + Postgres in Docker; the new
endpoints (fault translator, failed consumer, mark-track-as-failed) configure
and the bus starts clean.

Replace ~240 lines of hand-written per-endpoint wiring with MassTransit's
ConfigureEndpoints + KebabCaseEndpointNameFormatter, and apply retry + EF
outbox globally through AddConfigureEndpointsCallback. Adding a consumer or
activity is now a single AddConsumer/AddActivity line.
- Normalize the 4 mismatched activity endpoint names to kebab-case so the
routing-slip addressing keeps resolving (update-play-list-picture,
delete/mark/publish play-list variants); cleanup consumer queue is now
routing-slip-clean-up
- Drop the now-unused QueueName consts from event consumers and trim
EndpointHelper / delete the manual endpoint-config partial
Verified end-to-end: booted the Worker against RabbitMQ in Docker and
confirmed all 38 endpoints are configured with the exact names the builders
address (19 execute queues + compensations + consumers + routing-slip-clean-up).

Fix (recoverability bug):
- TransferFilesToBucketActivity returned Completed() with no log, so its
compensation could never delete the transferred files (orphaned objects on
fault). IStorageService.TransferFilesAsync now returns the real uploaded
keys; the activity logs them so Compensate can remove them. Also drops the
Path.Combine key recomputation (produced backslash keys on Windows).
Consistency / DRY:
- Normalize all courier activities to internal + folder-based namespaces
(several were public and in the flat .Activities namespace)
- Extract the duplicated exponential retry into UseStandardRetry
- Unify endpoint-name logic into a single EndpointHelper (remove the parallel
MassTransitEndpointNames helper)

- Move all .NET (6 projects, solution, Directory.*.props, nuget.config)
into backend/ so the monorepo root can host non-.NET projects later
- Remove throwaway test artifacts: player.html, pl.json
- Trim dead Flutter rules from .gitignore
Build from backend/Musify.slnx: 0 warnings, 0 errors.
