v1.3.6 feat: refactor change_config, optimize text() and unify TLS_SERVER handling

- Replace change_cdn() with change_config() supporting multi-field edits (CDN, Reality SNI, node name, UUID/password, server IP) via unified menu
- Rewrite text() with bash nameref + pre-scanned TEXT_NEEDS_EVAL map to eliminate per-call grep subprocesses
- Refactor ssl_certificate() to accept a TLS_SERVER parameter instead of using global TLS_SERVER_DEFAULT
- Remove per-protocol TLS_SERVER array; use single scalar read from cert SAN
- Localize cert fingerprint variables inside export_list()
- Bump version to v1.3.6 (2026.03.22)

v1.3.6 重构：统一修改入口 change_config、优化 text() 函数、统一 TLS_SERVER 处理

- 用 change_config() 替换 change_cdn()，通过统一菜单支持多项修改（CDN、Reality SNI、节点名、UUID/密码、服务器 IP）
- 用 bash nameref + 预扫描 TEXT_NEEDS_EVAL 关联数组重写 text() 函数，消除每次调用产生的 grep 子进程
- 重构 ssl_certificate()，改为接受 TLS_SERVER 参数，不再依赖全局变量 TLS_SERVER_DEFAULT
- 移除各协议独立的 TLS_SERVER 数组，改为从证书 SAN 读取统一标量
- 将证书指纹变量局部化至 export_list() 内部
- 版本升级至 v1.3.6 (2026.03.22)
