fix(dashboard): complete i18n support for shared components

[RC-CHN]

• Replace hardcoded Chinese strings with i18n translations in:

  • PluginSetSelector.vue
  • ProviderSelector.vue
  • PersonaSelector.vue
  • KnowledgeBaseSelector.vue
  • T2ITemplateEditor.vue
  • AstrBotConfigV4.vue
  • ConfigItemRenderer.vue
  • ProxySelector.vue
  • ListConfigItem.vue

• Add missing translations to locale files:

  • core/shared.json: personaSelector, t2iTemplateEditor
  • core/common.json: autoDetect
  • features/settings.json: network.proxySelector

• Change prop defaults from hardcoded Chinese to empty strings, allowing components to use i18n fallback translations

修复了面板上一部分未使用i18n的部分，添加相关翻译项。

改进共享仪表盘组件及相关配置选择器的国际化覆盖率。

Bug Fixes:

• 将共享仪表盘组件中硬编码的中文 UI 文本替换为基于 i18n 的翻译。
• 通过清除硬编码的中文默认属性文本，使共享选择器组件能够依赖 i18n。

Enhancements:

• 为 T2I 模板编辑器、角色选择器、插件集选择器、提供方选择器、知识库选择器、代理选择器以及列表配置项等共享组件添加模块级的 i18n 使用方式。
• 为共享组件、通用操作以及网络代理设置扩展本地化字典中缺失的键，以支持完整的多语言 UI。

Summary by Sourcery

Improve internationalization coverage for shared dashboard components and related configuration selectors.

Bug Fixes:

• Replace hardcoded Chinese UI strings in shared dashboard components with i18n-backed translations.
• Allow shared selector components to rely on i18n by clearing hardcoded Chinese default prop texts.

Enhancements:

• Add module-scoped i18n usage for shared components such as T2I template editor, persona selector, plugin set selector, provider selector, knowledge base selector, proxy selector, and list config items.
• Extend locale dictionaries with missing keys for shared components, common actions, and network proxy settings to support full multilingual UI.

Hey - 我发现了 1 个问题，并给出了一些总体反馈：

• 对于 ListConfigItem.vue，现在 buttonText 和 dialogTitle 默认值为空字符串，建议添加基于 i18n 的兜底文案（类似其他 selector 组件），这样这些 props 即使在调用方未显式传入时，也依然有合理的默认值。
• 在 PersonaSelector.vue 中，你新增加了一个单独的 personaSelector.cancelSelection 文案键，而其他对话框复用的是 core.common.cancel/confirm；建议这里也复用这些公共键，以便在所有对话框中保持一致性。

给 AI Agent 的提示词

Please address the comments from this code review:

## Overall Comments
- For `ListConfigItem.vue`, now that `buttonText` and `dialogTitle` default to empty strings, consider adding i18n-backed fallbacks (similar to the selector components) so these props still have sensible defaults without relying on callers.
- In `PersonaSelector.vue`, you introduced a dedicated `personaSelector.cancelSelection` key while other dialogs reuse `core.common.cancel`/`confirm`; consider reusing the shared common keys here as well for consistency across dialogs.

**suggestion:** 将特定语言的标点放在翻译之外会降低本地化的灵活性。

当前模板中冒号仍然是硬编码的，而只有标签文本被本地化，这会把 UI 绑定到中文的全角冒号形式。建议将冒号移入翻译字符串中，这样每个语言环境就可以自行决定使用什么标点和空格格式。

建议实现方式：

```
                <div class="plugins-header">
                  <small class="text-grey">{{ t('core.shared.pluginSetSelector.selectedPluginsLabel') }}</small>
                </div>

```

要完整实现这一建议，请更新你的 i18n 资源文件，使 `core.shared.pluginSetSelector.selectedPluginsLabel` 在各个语言环境中都包含适当的标点，例如：
- Chinese: `"selectedPluginsLabel": "已选择的插件："`  
- English: `"selectedPluginsLabel": "Selected plugins:"`

Hey - I've found 1 issue, and left some high level feedback:

• For ListConfigItem.vue, now that buttonText and dialogTitle default to empty strings, consider adding i18n-backed fallbacks (similar to the selector components) so these props still have sensible defaults without relying on callers.
• In PersonaSelector.vue, you introduced a dedicated personaSelector.cancelSelection key while other dialogs reuse core.common.cancel/confirm; consider reusing the shared common keys here as well for consistency across dialogs.

**suggestion:** Embedding locale-specific punctuation outside the translation makes localization less flexible.

The colon remains hard-coded in the template while only the label is localized, tying the UI to a Chinese-style full-width colon. Move the colon into the translation string so each locale can choose its own punctuation and spacing.

Suggested implementation:

```
                <div class="plugins-header">
                  <small class="text-grey">{{ t('core.shared.pluginSetSelector.selectedPluginsLabel') }}</small>
                </div>

```

To fully implement the suggestion, update your i18n resource files so that `core.shared.pluginSetSelector.selectedPluginsLabel` includes the appropriate punctuation for each locale, for example:
- Chinese: `"selectedPluginsLabel": "已选择的插件："`  
- English: `"selectedPluginsLabel": "Selected plugins:"`
</issue_to_address>
