fix(challenge,scene): challenge id auto-detect, real ScRsp ids, teleport ownership

Round-2 fixes from the 01:44-01:53 client session:

- StartChallenge (MoC/PF/AS normal start) decoded challenge_id=0 -> client
  retried and aborted. detectChallengeID scans top-level varints for the
  first plausible id (challenge_data + known mode ranges) when the strict
  tag-14 decode misses; payload hexdump logged when still 0
- StartChallengeScRsp now carries stage_info (tag 13) with boss node buff
  echo, per the 4.6.51 proto
- GetSwitchHandData replies 8108 (the real ScRsp) - 8104 is
  SwitchHandStartCsReq, we were sending a request id back at the client
- GetSceneMapInfo: strict proto parse failed on some payloads (layout
  drift) which stalled the map UI ('no pillars / navigation loading') -
  now a raw handler with a lenient wire walk fallback + hexdump logging
- teleport destination ('AA teleport landed in AP'): teleport ids repeat
  on every floor and teleports.json was scanned globally in random map
  order. Map clicks now resolve floor-first via scene_identifier, and the
  global id scan never touches teleports.json
- tierce: arena 3014101 -> 3000101 fallback (client has no MapEntrance
  3014101), same as StartChallenge
