game: fix SMSG_SPELL_GO miss-entry consumption in WotLK and TBC parsers

Both SpellGoParser::parse (WotLK) and TbcPacketParsers::parseSpellGo
(TBC) read missCount but did not consume the per-miss (guid + missType)
entries that follow, leaving unread bytes in the packet and silently
corrupting any subsequent parsing of cast-flags–gated spell data.

- Add SpellGoMissEntry{targetGuid, missType} and missTargets vector
  to SpellGoData
- WotLK parser now reads packed GUIDs + missType per miss entry
- TBC parser now reads full uint64 GUIDs + missType per miss entry
  (9 bytes per entry, bounds-checked)
- handleSpellGo now shows MISS/DODGE/PARRY/BLOCK combat text
  for each missed target when the local player cast the spell,
  complementing the existing SMSG_SPELLLOGMISS path
- Remove unused foliageLikeModel variable in m2_renderer pass-2 loop
  (fix unused-variable warning)
- Update smoke model comment in m2_renderer to reflect current state
