● fix(ams): restore Configure/Assign actions on reset slots + relax Assign Spool filtering (#1047)

Three related fixes reported together:

  (1) After resetting an AMS slot, the printer card showed "Empty Slot"
  with no Configure or Assign Spool actions while SpoolBuddy's AMS page
  still let the user re-configure the same slot. Commit c9efa4b8 (#784)
  added a `tray?.state === 10` gate to the EmptySlotHoverCard actions,
  intended to hide them on physically-empty slots (state=9). In practice
  firmware often reports state=9 (or omits state entirely) after a
  user-initiated reset even when a spool is still present, so the gate
  hit the wrong case. The gate was redundant anyway — EmptySlotHoverCard
  only renders when tray_type is empty — so it's removed at both the
  standard-AMS and AMS-HT render paths.

  (2) After configuring a slot with a Generic profile, the Assign Spool
  modal hid manually-added inventory spools even when material matched,
  unless the user flipped "Show all spools". The filter required exact
  slicer_filament_name equality, which manually-added spools don't
  populate. Filter now prefers exact slicer-profile match when both
  sides have one, and falls back to partial material match in either
  direction (so a "PLA" spool shows up for a "PLA Basic" slot).

  (3) On assign, the mismatch dialog fired on every Generic spool
  because Bambu Studio / OrcaSlicer profile names carry an @printer
  nozzle (variant) qualifier while the tray stores the bare base name.
  Both the filter and checkProfileMatch now strip everything from @
  onward before comparing.

  Adds 3 regression tests covering each path.
