fix(armor): correct armor count in EKFParameters

[heyeuu]

修正装甲板数目的逻辑，移除平衡步兵

修复装甲板数目逻辑

本 PR 修正了 EKFParameters::armor_num() 方法中的装甲板计数逻辑。

主要改动

在 src/module/predictor/ekf_parameter.hpp 文件中，简化了 armor_num(DeviceId const&) 方法的实现：

• 移除了对"平衡步兵"的特殊处理：之前存在一个条件分支，当检测到"平衡步兵"设备类型时会返回装甲板数为 2，现已删除此逻辑
• 删除了本地变量 is_balance 及其关联的条件判断分支
• 统一了非哨兵/非基地设备的装甲板数：所有不是 OUTPOST 或 BASE 的设备现在都统一返回装甲板数为 4

当前实现

static auto armor_num(DeviceId const& device) -> int {
    auto num = int {};
    if (device == DeviceId::OUTPOST || device == DeviceId::BASE) num = 3;
    else num = 4;
    return num;
}

装甲板计数规则现为：

• 哨兵 (OUTPOST)：3 块
• 基地 (BASE)：3 块
• 其他设备：4 块

影响范围

代码改动仅涉及 EKF 参数配置文件，未有公共接口签名变化。

漫步

移除了 EKFParameters::armor_num() 函数中针对步兵单位的条件分支，统一将非哨兵和非基地的设备装甲数直接设为默认值 4，删除了 is_balance 局部变量及其相关逻辑。

变更

组队/文件	概述
装甲数参数简化 src/module/predictor/ekf_parameter.hpp	移除了 armor_num() 函数中设备类型条件判断，删除了针对步兵的特殊装甲数赋值（原为 2）以及 is_balance 变量逻辑，改为对所有非特殊设备统一应用默认装甲数 4。

🐰 装甲数归整齐，条件分支一扫去，
步兵皆同四套甲，逻辑简洁又通透，
删行三两显风采！
