## Summary
- Upgrade Transmission from 4.0.6-r4 to 4.1.1-r1
- Uses Alpine edge community repo for transmission packages, keeping stable alpine:3.22 base
- Fix stale image reference in service doc (was linuxserver, now custom registry image)
- Mark transmission as reviewed in service-versions.yaml
## Context
Service review found Transmission two minor versions behind (4.0.6 → 4.1.1). Alpine 3.22 only packages 4.0.6, so transmission is installed from edge's community repo with an exact version pin.
4.1.0 added improved µTP performance, IPv6/dual-stack UDP tracker, JSON-RPC 2.0 API. 4.1.1 is a bugfix release (20+ fixes).
Dagger test build passed locally.
## Deployment and Testing
- [ ] Build container via Forgejo workflow (`mise run container-build-and-release transmission`)
- [ ] Update kustomization.yaml with new image tag
- [ ] `argocd app set torrent --revision feature/transmission-review && argocd app sync torrent`
- [ ] Verify web UI at https://torrent.ops.eblu.me
- [ ] Check Grafana Transmission dashboard still receives metrics
- [ ] After merge: `argocd app set torrent --revision main && argocd app sync torrent`
## Note
The transmission-exporter sidecar (OOMKilling every ~30min, 294 restarts) is being tracked separately as a future replacement project.

## Test plan
- [ ] Anonymous pull still works
- [ ] Unauthenticated push fails (401)
- [ ] CI container builds pass with new auth and tagging
- [ ] `mise run services-check` passes
