fix(dashboard): use v-autocomplete for list+options config field (#7884)

[10knamesmore]

close #7884

Modifications / 改动点

将插件配置中 list + options 字段的渲染组件从 Vuetify v-select 替换为 v-autocomplete：在多选场景下，键入字符不再触发 v-select 内置的"键盘 typeahead 自动 toggle 首个前缀匹配项"行为（该行为对长 options 列表完全不可用，例如 astrbot_plugin_repo_of_today 中含上千项的语言选择字段），改为按输入文本过滤下拉候选。

同时新增本地 listSearchText ref，通过 v-model:search 绑定，并在 @update:model-value 中清空，使每次选中后搜索框自动重置，可连续键入下一个关键词搜索而无需手动退格。

修改文件

• dashboard/src/components/shared/ConfigItemRenderer.vue — 将 type === 'list' && options 分支由 v-select 改为 v-autocomplete，新增 listSearchText ref 与选中清空逻辑。

未改动：单选 v-select 分支、render_type: 'checkbox' 渲染变体、checkbox 与其他 schema 类型分支。

• This is NOT a breaking change. / 这不是一个破坏性变更。

Screenshots or Test Results / 运行截图或测试结果

修改前， 选中python 后输入ty, python chip被覆盖， 并且自动选中typesciprt, 忽略后面的typst 等等

修改后,

会只进行字符串匹配， 并且不自动选中

Summary by Sourcery

Improve dashboard plugin list option selection by switching to an autocomplete-based multi-select with better search behavior.

Bug Fixes:

• Prevent multi-select list option fields from unintentionally toggling and overwriting selections when typing in large option sets.

Enhancements:

• Use an autocomplete input for list+options configuration fields to support inline text filtering and automatic clearing of the search term after each selection.

Hey - I've left some high level feedback:

• Consider extracting the inline @update:model-value="val => { emitUpdate(val); listSearchText = '' }" into a named handler in the script block so the template stays simpler and you avoid recreating the function on each render.

Code Review

This pull request updates ConfigItemRenderer.vue by replacing v-select with v-autocomplete to support searching within list-type configuration items. The review identifies a performance concern where the items list is re-processed on every keystroke and suggests using a computed property to optimize rendering. A UX improvement was also proposed to include closable-chips for easier removal of selected items in multi-select mode.
