UI: upload panel — POST /jobs with live status polling

Adds a "+ wgraj" control to the sidebar that uploads an ISO/ZIP/DLL to the
acquisition endpoint and tracks the job to completion, then refreshes the
version list so the new snapshot appears without a reload.

- index.html: upload form + #jobs panel in the sidebar
- app.js: submitUpload() (FormData → POST /jobs), pollJobs() (2.5s while any
  job is queued/started; finished → load(); failed → inline error)
- style.css: mini-btn / upload form / job rows + queued/started badges

Verified: node --check clean; uvicorn serves /ui assets 200 and GET /jobs.
