fix: clear spell queue in stopCasting; fix SMSG_SPELL_DELAYED castTimeTotal; clear cast on same-map res

- stopCasting() (invoked by /stopcasting) now clears queuedSpellId_/
  queuedSpellTarget_ and craftQueueSpellId_/craftQueueRemaining_ so a
  queued spell cannot fire silently after the player explicitly cancels.
- SMSG_SPELL_DELAYED now extends castTimeTotal alongside castTimeRemaining
  for the local player, matching the existing other-unit handling and
  keeping the cast bar progress percentage accurate after server-imposed
  cast delays.
- Same-map resurrection path (SMSG_NEW_WORLD same-map) now resets casting,
  castIsChannel, currentCastSpellId, castTimeRemaining, and the spell queue
  as a defensive measure (player is dead and cannot be casting, but this
  ensures state is clean on respawn).
