fix(ui): improve date input parsing and add missing back navigation (#284)

## Summary
- Improve DatePicker text parsing to accept more input formats
(including `YYYYMMDD`) without requiring explicit separators
- Add missing H5 back-navigation for panel-sharing by using simple
layout route
- Add a back button on config page with history fallback (`navigate(-1)`
then `/profile`)

## Why
These are usability/accessibility improvements that are generic and not
project-brand specific:
- Mobile keyboards may not easily input `-` in date fields
- Certain pages in H5 lacked a consistent return path
- Config page had no explicit in-page back action

## Scope
- `vite-frontend/src/shadcn-bridge/heroui/date-picker.tsx`
- `vite-frontend/src/App.tsx`
- `vite-frontend/src/pages/config.tsx`

## Notes
No branding/identity/ownership/visual-theme customizations included in
this PR.

+我已经定位到问题点了，确实在后端 `forward/update` 的限速校验会把“已被删除的限速ID”当成硬错误返回，导致你说的二次编辑报 `限速规则不存在`。
+
+**定位结果**
+- 触发点在 `go-backend/internal/http/handler/mutations.go:1259` 附近（`forwardUpdate`）和 `go-backend/internal/http/handler/mutations.go:1147` 附近（`forwardCreate`）。
+- 当前逻辑是：只要请求里带了 `speedId`，且 `SpeedLimitExists=false`，就直接 `ErrDefault("限速规则不存在")` 返回。
+- 前端编辑提交在 `vite-frontend/src/pages/forward.tsx:1403` 会一直带 `speedId`（包括编辑场景），所以很容易复现你说的问题。
+
+**实施计划（不改动其他业务）**
+- 新建计划文档：`plans/006-forward-save-missing-speed-limit-auto-clear.md`（按现有 001~005 递增）。
+- 后端仅改转发保存逻辑，不改用户隧道限速逻辑：
+  - `forwardCreate`：若 `speedId` 不存在，自动当成 `nil`（即“不限速”）继续保存，不返回“限速不存在”错误。
+  - `forwardUpdate`：按“最终要写入的 speed_id”做一次兜底校验；若不存在则自动清空为 `NULL` 再继续保存，确保编辑不阻断。
+- 不新增“限速不存在”阻断提示（符合你要求）。
+- 增加/更新合约测试：`go-backend/tests/contract/forward_contract_test.go`
+  - 覆盖场景：转发绑定限速后，删除该限速，再编辑转发保存，应返回成功且 `forward.speed_id` 被清空。
+- 验证命令（实施后执行）：
+  - `cd go-backend && go test ./tests/contract/... -run Forward`
+  - 如有必要再跑 `cd go-backend && go test ./...`
+
+如果你确认，我下一步就按这个方案进入实现。

+你这个新报错我确认了：这次**不是端口占用问题**，是 **IP 本机不可绑定** 问题。
+
+- 报错是 `bind: cannot assign requested address`，含义是节点机器网卡上没有 `13.228.170.187` 这个本地地址；释放旧服务也不会解决。
+- 你说“唯一一个IP可选”，很可能来自前端当前候选逻辑把 `serverIp/serverIpV4/serverIpV6` 当成监听候选（`vite-frontend/src/pages/forward.tsx:612` 一带），但这些字段在 NAT/云环境下常是“对外地址”，不一定是本机可 bind 地址。
+- 我之前加的自占用释放逻辑会在冲突时尝试删旧服务再加新服务，但对 `cannot assign requested address` 这种错误会一直失败（因为 IP 本身不可绑定）。
+
+我建议下一步这样改（这次是关键）：
+
+- 后端只把 `address already in use` 走“自占用释放重绑”流程；`cannot assign requested address` 不走该流程。  
+  位置：`go-backend/internal/http/handler/control_plane.go`
+- 前端监听 IP 下拉改为“可绑定地址优先”：优先 `extraIPs` + 明确配置的监听地址，**不再默认把 `serverIp*` 作为可绑定监听IP**。  
+  位置：`vite-frontend/src/pages/forward.tsx`
+- 后端增加快速校验并返回更明确提示：  
+  `监听IP不是节点本机地址，请在节点 extraIPs 配置可绑定IP后再选择`。  
+  位置：`go-backend/internal/http/handler/control_plane.go` + repo 查询辅助。
+- 你的临时可用绕过：到节点配置里把真实网卡 IP 填到 `extraIPs`，然后在编辑转发时选该 IP。
+
+一个需要你拍板的点（推荐第1个）：
+
+1. **推荐**：前端不再展示 `serverIp/serverIpV4/serverIpV6` 为监听IP候选，只展示 `extraIPs`（和明确监听地址）。  
+2. 继续展示 `serverIp*`，但加“可能不可绑定”标签和失败提示。  
+
+你回我 `1` 或 `2`，我就按这个继续落地。

+你这个判断是对的，我已经把链路看清了，确实是“新增自定义监听 IP 后，编辑保存把原监听状态覆盖掉”导致的。
+
+- 前端编辑表单会把 `forward.inIp` 直接回填到 `form.inIp`（`vite-frontend/src/pages/forward.tsx:1302`）。
+- 保存时会把 `form.inIp` 带到更新请求（`vite-frontend/src/pages/forward.tsx:1391`）。
+- 后端更新时无论是否真的改了监听 IP，都会用请求里的 `inIp` 全量重建 `forward_port`（`go-backend/internal/http/handler/mutations.go:1288`、`go-backend/internal/http/handler/mutations.go:1305`、`go-backend/internal/http/handler/mutations.go:3019`）。
+- 而列表里的 `forward.inIp` 可能是“展示回退值”（隧道 IP/节点 IP），不一定是原始 `forward_port.in_ip`（`go-backend/internal/store/repo/repository.go:731`、`go-backend/internal/store/repo/repository.go:2778`、`go-backend/internal/store/repo/repository.go:2780`）。
+- 这样就会在“没手动选监听 IP”时，把服务改成绑定不可用地址，触发 `bind: cannot assign requested address`。
+
+我建议的修复方案（实现时会做成双保险）：
+
+- 前端：编辑模式下仅当用户“主动改过监听 IP”时才提交 `inIp` 字段；未触碰则不传，保持原状态。
+- 后端：`forward/update` 中如果请求没带 `inIp`，就保留原 `forward_port.in_ip`（不清空、不覆盖）；若带了 `inIp`（包括空串），按用户意图更新。
+- 回归测试：
+  - 后端新增用例：未传 `inIp` 时更新不改变监听绑定。
+  - 后端新增用例：显式传空串时清空监听绑定。
+  - （可选）前端补充一个轻量逻辑测试/至少手工验证路径。
+
+另外按仓库规则，这次会新增计划文档为：`plans/003-forward-edit-bind-ip-preserve.md`（当前是只读 Plan Mode，我还没动文件）。
+
+一个需要你拍板的小点（我给默认建议）：
+- **推荐默认**：编辑时如果改了隧道但没有手动选“监听IP”，按“默认监听（空）”处理，不继承旧隧道的监听 IP。  
+  这样能避免把旧隧道的 IP 误带到新隧道。  
+  你是否同意按这个规则？

+# 004 Forward Explicit Bind Self-Occupy Release
+
+## Checklist
+
+- [x] Confirm current forward edit/save failure path and lock strategy: explicit bind always stays explicit.
+- [x] Add repository query to detect whether a node+port is occupied by other forwards (excluding current forward).
+- [x] Enhance forward service sync to treat address-in-use as a recoverable case when only self occupies the port.
+- [x] On self-occupy conflict, proactively delete current forward services on target node and retry AddService.
+- [x] Keep hard failure when the same node+port is occupied by other forwards.
+- [x] Add focused unit tests for new error classification helpers.
+- [x] Run focused backend tests for touched handler/repo packages.

+## 背景
+
+当前系统允许普通用户在创建和编辑转发时设置：
+1. **限速规则** (`speedId`) - 应仅限管理员设置

+
+普通用户应只能使用系统自动分配的端口和默认不限速设置。
+
+## 实施范围
+
+| 操作 | 普通用户 | 管理员 |
+|------|----------|--------|
+| 创建转发 - 设置限速 | 禁止 | 允许 |
+| 创建转发 - 自定义端口 | 禁止 | 允许 |
+| 编辑转发 - 修改限速 | 禁止 | 允许 |

+# 011 转发服务名升级兼容与节点滚动升级
+
+## 目标
+- 修复旧版本升级后编辑转发/隧道出现 `service not found`（service不存在）的问题。
+- 在后端加入兼容自愈逻辑，允许旧命名与新命名共存过渡。
+- 给出低风险节点升级顺序，避免一次性全量切换带来的中断。
+
+## Checklist
+- [x] 定位回归路径：服务名从 `forward_user_0` 迁移到真实 `user_tunnel_id` 后，与旧运行态不一致导致控制失败。
+- [x] 在 `UpdateService` 的兼容路径加入旧服务清理后重建逻辑。
+- [x] 在 `Pause/Resume` 控制路径加入首次 not found 后自愈重试逻辑。

+
+## 测试记录
+- 命令：`cd go-backend && go test ./internal/http/handler/...`

+
+## 运维升级顺序（推荐）
+1. 先发布本次后端兼容补丁（无需等待所有 agent 同步升级）。
+2. 按 10%-20% 灰度分批升级 agent（低风险节点 -> 非高峰节点 -> 全量）。
+3. 每批升级后执行一次“转发批量重部署”，将运行态统一到新服务命名。
+4. 观察日志中 `service .* not found` 是否清零，再推进下一批。
+5. 全量稳定后保留兼容逻辑至少一个小版本周期，再评估收敛。

+# Plan 012: 允许用户自定义转发入口端口（限制在节点端口范围内）
+
+**Issue**: #268  
+**状态**: 已完成
+
+## 背景
+
+当前版本限制了普通用户自定义转发入口端口 (inPort) 的能力，导致：
+- 用户迁移数据后无法保留原有端口配置
+- 无法编辑转发配置
+- 需要重建所有转发，操作繁琐
+
+## 实现方案
+
+允许用户和管理员自定义转发入口端口，但强制在节点端口设置的范围内。
+
+### 默认行为
+- 不填写端口 → 随机分配（在端口范围内）
+- 填写端口 → 使用指定端口（需在范围内且不冲突）
+
+---
+
+## 任务清单
+
+### 1. 后端修改

+## Investigation Note
+
+- Forward update still has its own independent `address already in use` recovery path in `syncForwardServicesWithWarnings` / `rebindForwardServiceOnSelfOccupiedPort`; tunnel update linkage is not the only possible source of the symptom.
+- Tunnel update also triggers downstream forward `UpdateService` for bound forwards, so users can still observe the same error around a tunnel edit even when the failing runtime is on the tunnel side.
+- Real node output can collapse spaces into variants like `address alreadyin use` / `cannotassignrequestedaddress`; bind-conflict detection now normalizes whitespace before classifying the error.
+- Forward self-heal cleanup now deletes every candidate runtime name variant instead of stopping after the first successful delete, which avoids leaving sibling `_tcp`/`_udp` services behind to keep the port occupied.
