Add roaster (machine) management, mobile header-tools redesign, and profile pictures

Machines:
- roasters table + actual_roasts.roaster_id (migrations 009): per-user
  machines with a default; uploads attach to the default roaster and are
  reassignable from the roast detail view
- Learning is now per machine: /api/roaster-profile scopes to a roaster
  (default when unspecified) and applies the user's override tweaks
  (milestone temps, TP time, pace factor) on top of learned medians
- /roasters page: machine list + analysis report showing learned vs
  applied values with editable tweaks, typical RoR, and a plain-language
  list of the adjustments applied to plans; planner honors a manual pace
  override; evaluations use the roast's own machine profile

Mobile header redesign:
- The planner's header tools collapse behind a single 'Tools ▾'
  disclosure (dropdown card) at ≤720px, keeping the fixed three-row
  mobile header with no wrapped or scrolling button rows; desktop
  renders inline via display:contents (same DOM, same handlers)

Profile pictures:
- users.avatar (migration 010) + PUT/GET/DELETE /api/account/avatar;
  client-side centre-crop resize to 128px JPEG; avatar shows in the nav
  chip on every page; included in full backups
