fix(live): 修复上麦 goUp 的 NPE 风险、异常吞噬和重复 HTTP 调用

P0 - BUG 修复:
- 将 liveMicrophone 和 micUser 的 null 检查移至使用前，彻底消除 NPE 风险
- 替换 catch(Exception) 全吞逻辑：业务异常直接上抛保留原始错误码，
  不再将所有错误误报为"麦克风已被占用"，改用 log.error 记录完整堆栈

P1 - 性能优化:
- checkMicAvailableUse 前移至加锁后第一步，麦位已占时提前返回，
  避免后续 5 次 HTTP 调用空跑
- userProfileClient.getByUserId 由 2 次减为 1 次：
  先获取 UserProfileDTO 后直接传给 toLiveMicUser，
  删除 getLiveMicUser 内部的重复调用
