maziggy 4b0150b0ec fix(mqtt): close #1822 — promote H2S tray_now to 254 on all-external prints ...

H2S firmware reports tray_now=0 (the AMS's idle slot) throughout
  external-spool prints instead of 254 like X1C/P1S/A1 do, so the
  single-nozzle branch's 0-3 passthrough landed state.tray_now on slot
  0 — UI highlighted AMS SLOT 1 instead of the external spool.
  Usage credit was unaffected (#1276 covers that via ams_mapping).

  The single-nozzle branch now checks _captured_ams_mapping (slicer-
  captured per-filament mapping that the request-topic intercept
  already tracks) before the existing P2S multi-AMS resolver. When
  every entry is -1, the print uses ONLY the external spool, so
  state.tray_now is promoted to 254.

  Narrow on purpose: AMS-only [5] and mixed [5, -1] are NOT
  overridden — we have no evidence H2S misreports mid-print swaps, and
  trusting the firmware preserves correctness for users with multi-
  filament setups. No-mapping prints (printer-screen start) fall
  through unchanged.
