Missing tooltips in ChatInterface header & input buttons

[KiKaraage]

When customizing Shelley, I noticed some buttons are missing tooltips, especially on the chat header and input area (New Conversation, menu button, attach files, voice record, Send). Then I also notice that Delete Conversation button for archived conversation uses browser tooltip instead of Shelley-styled tooltips.

I consult and got some findings:

• These buttons in ChatInterface, MessageInput, and ChatOverflowMenu has aria-label but not v-tooltip, which is required for Vue/PrimeVue. This seems to be unsolved during migration from React to Vue.
• The "Restore" button in ConversationDrawerRow uses v-tooltip.top="ctx.t('restore')" and gets PrimeVue styling. The "Delete Permanently" button lives in the DeleteButton render function as a plain h() vnode with title: ctx.t("deletePermanently"), so it gets the browser's native tooltip instead.

I asked further and found more buttons that hasn't had v-tooltip covered, here's the full list (including the points above):

• ChatInterface & MessageInput
  • ChatInterface.vue — .btn-new (newConversation), hamburger (openConversations), overflow kebab trigger (moreOptions)
  • MessageInput.vue — attach, voice, send (both split-main and regular)
• ConversationDrawer (for mobile header buttons)
  • newConversation button (line ~120)
  • closeConversations button (line ~136)
• ConversationDrawerRow — DeleteButton render function
  • "Delete Permanently" trash button, plus the confirm-state delete/cancel buttons (all use raw title:)
• MessageActionBar (though it uses data-tooltip="Copy" instead of v-tooltip)
  • Copy button (line ~9)
  • Fork conversation from here button (line ~44)
  • Details button (line ~68)
• CommitPicker
  • Trigger button (line ~16)
  • Close button (line ~41)
• Modal
  • Close modal button (line ~34)
• All tool collapse/expand buttons (20 components)
  • Every tool component's Collapse/Expand toggle button — BashTool, GenericTool, ThinkingContent, SubagentTool, BrowserConsoleLogsTool, BrowserEmulateTool, BrowserEvalTool, BrowserNavigateTool, BrowserNetworkTool, BrowserProfileTool, BrowserResizeTool, BrowserScreencastTool, BrowserAccessibilityTool, ChangeDirTool, KeywordSearchTool, LLMOneShotTool, ReadImageTool, ScreenshotTool, WebSearchTool, SystemPromptView.
• OutputIframeTool
  • Download button (line ~36)
  • "Open in new tab" button (line ~58)
• PatchTool (renamed from DiffPatchTool?)
  • "Open in editor" button (line ~47)
  • Side-by-side/inline toggle (line ~70)

My own patch haven't covered the full list, only the chat header & input buttons, so feel free to implement it!
