feat(printers): sort by ETA (#1609)

  Adds an "ETA" option to the Printers page sort dropdown.
  Sorts the fleet by remaining print time so the printer that's
  finishing next sits at the top — useful for staging the next
  job's filament ahead of time.

  Tier ordering:
  - Tier 0: currently printing with remaining_time > 0
    (sorted ascending by remaining minutes)
  - Tier 1: currently printing without an ETA yet
    (post-start_print window before total time is known)
  - Tier 2: idle / finished
  - Tier 3: offline
  Name tiebreaker within every tier. The asc / desc arrow
  still applies after tiers resolve.

  Data source is the cached remaining_time (minutes) on the
  per-printer status query — the same field the per-card ETA
  label and the fleet "next finish" badge already read from.
  No new backend round-trip; the sort consumes data that's
  already in React Query cache and updated on every WebSocket
  push.

  groupedPrinters returns null for ETA too — every printer's
  ETA is unique so section headers would just produce a header
  per row. Flat list, like the existing name sort.
