maziggy 554a73070f fix(maintenance): paused prints no longer accumulate runtime hours (#1521)
PAUSE counted toward runtime_seconds equally with RUNNING, inflating
  hours-based maintenance thresholds (rod lube, belt check, nozzle clean)
  by however long overnight or extended pauses lasted. Maintenance items
  track mechanical wear, which is zero while paused, so the predicate
  now excludes PAUSE. Field-comment and docstring trail across main.py /
  models/printer.py / maintenance.py updated to match. Existing
  runtime_seconds values cannot be retroactively split — only future
  accumulation is fixed.

  Adds 3 regression tests pinning PAUSE non-accumulation, RUNNING
  accumulation, and the FINISH state's last_runtime_update clear
  (prevents idle-time back-bill when the printer next goes RUNNING).
