fix: refresh cached miniapp urls

[mturac]

What this PR does

Before this PR:

Opening a keep-alive mini-app with an existing id reused the cached app config without refreshing its URL. Dynamic mini-app URLs, including the OpenClaw dashboard URL with its auth token, could therefore reopen with a stale tokenless URL.

After this PR:

Keep-alive mini-app opens always refresh the cached config before showing the app. Existing OpenClaw dashboard tabs now receive the latest tokenized URL from getDashboardUrl().

Fixes #14415

Why we need it and why it was done in this way

The following tradeoffs were made:

This keeps the fix in the shared mini-app cache path instead of adding OpenClaw-specific reload code, so every dynamic mini-app URL benefits from the same behavior.

The following alternatives were considered:

Closing and recreating the OpenClaw dashboard tab on every open was considered, but refreshing the cached config is smaller and preserves the existing keep-alive behavior.

Code Review: LGTM ✅

变更精准修复了 #14415，符合 hotfix 最小范围原则。

核心改动: 将 mini-app 缓存策略从"仅缓存新条目"改为"始终刷新缓存"，确保动态 URL（如 OpenClaw 带 auth token 的 dashboard URL）在重新打开时获取最新 URL。

审查要点:

• ✅ 正确性: LRUCache.set() 对已有 key 原地更新，行为正确
• ✅ 安全性: 确保 auth token 每次打开时刷新，避免使用过期 token
• ✅ 性能: 移除不必要的 get() 调用，set() 同样会将条目移到最近使用位置
• ✅ 一致性: 两处改动（openMinapp 和 openSmartMinapp）保持相同模式
• ✅ CI 全部通过

该 PR 成功修复了 OpenClaw 等动态小应用 URL 刷新滞后的问题。通过强制更新缓存，确保了 Token 的实时性。建议在 \useMinappPopup\ 中增加配置变化检查，以避免在 URL 未变动时触发不必要的组件重绘或 WebView 重新加载。此外，注意到 Tab 模式下部分状态同步可能存在微小延迟，但不影响核心功能修复。

[B1] 每次调用 \openMinapp\ 都会触发 \minAppsCache.set\，即便 \�pp\ 的配置（特别是 \url\）没有发生变化。这会导致 Redux 状态产生新的引用并触发相关组件重绘，对于已打开的 WebView 也会导致其重新加载。建议在 \set\ 之前检查 \url\ 是否变化以避免不必要的重载。

[B1] 同上，在 \openSmartMinapp\（Tab 模式）中，点击已激活的 Tab 也会触发强制刷新。建议增加变化检查以保持与其它 Tab 系统一致的交互体验。
