refactor(api-v13): v3 路由按领域拆分，类收进 V3 子命名空间

两件互相咬合的整理，一起做。

路由：routes/api.php 里 v2 有 156 条声明、134 行 import，v3 铺开后还要翻倍。
v3 组按领域拆成 routes/v3/{system,search,tipitaka,channel,interaction}.php，
与 dashboard-v6/src/components/ 的领域对齐。前缀与名字前缀只在入口加一次，
子文件是扁平的路由列表。三条约定写进了入口注释：子文件不要再包一层 group
（漏写会让路由落到 /api/ 根下而且不报错）、不要用 glob（跨文件顺序要显式可读）、
按需建文件不要一次建十几个空的。

命名空间：v3 的类全部进 App\Http\{Controllers,Resources,Requests}\V3\，
类名不再带 V3——命名空间已经说明了版本，再带一次是冗余，而且跟 v2 同名也不
冲突（HeartbeatController 两边并存）。目录名用 StudlyCase 的 V3，PSR-4 要求
目录与命名空间段一致，仓库里的先例是 Library/。

判据：/v3/* 路由指向的控制器，全都应该在 Controllers/V3/ 下。所以除了 5 个带
V3 后缀的，另外 4 个（SearchPlus / SearchSuggest / Upgrade / Progress）也一并
搬了——它们名字里没有 V3，但逐个 grep 确认只被 v3 路由引用。

基类 V3Resource / V3ResourceCollection 改名 V3\BaseResource /
BaseResourceCollection（在 V3 命名空间里再带 V3 是重复）。
