feat(console): persist auto-scroll toggle state in localStorage

[RC-CHN]

The auto-scroll toggle on the console page resets to its default (true) on every page refresh, which can be annoying for users who prefer to keep it disabled.

Modifications / 改动点

dashboard/src/views/ConsolePage.vue

• Initialize autoScrollEnabled from localStorage on mount, falling back to true when no stored value exists.

• Watch autoScrollEnabled and persist changes to localStorage so the preference survives page reloads.

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

New Features:

• Remember the console auto-scroll toggle state per user by storing it in local storage and restoring it on page load.

Hey - I've left some high level feedback:

• Consider initializing autoScrollEnabled from localStorage in a mounted hook instead of in data() so the component doesn’t touch window.localStorage during server-side rendering or non-browser usage.
• It may be safer to normalize the stored value explicitly (e.g., const stored = localStorage.getItem('console_auto_scroll'); this.autoScrollEnabled = stored === null ? true : stored === 'true';) to avoid unexpected behavior if the key is ever set to an unexpected string.

## Overall Comments
- Consider initializing `autoScrollEnabled` from `localStorage` in a `mounted` hook instead of in `data()` so the component doesn’t touch `window.localStorage` during server-side rendering or non-browser usage.
- It may be safer to normalize the stored value explicitly (e.g., `const stored = localStorage.getItem('console_auto_scroll'); this.autoScrollEnabled = stored === null ? true : stored === 'true';`) to avoid unexpected behavior if the key is ever set to an unexpected string.

Code Review

This pull request implements persistence for the console's auto-scroll setting by storing the state in localStorage. The review feedback identifies potential runtime errors if localStorage is restricted and suggests wrapping storage operations in try-catch blocks. Additionally, it notes a synchronization issue where the initial persisted state is not correctly propagated to the child component upon mounting.

Accessing localStorage can throw an error if it is disabled or restricted in the user's browser. It is safer to wrap this call in a try-catch block to prevent the component from failing to mount.

autoScrollEnabled: (() => {
  try {
    return localStorage.getItem('console_auto_scroll') !== 'false';
  } catch (e) {
    return true;
  }
})(),

The autoScrollEnabled state is not synchronized with the ConsoleDisplayer component on initial load. ConsoleDisplayer defaults to true, so it will ignore the persisted false state until the user toggles the switch. Consider adding a mounted hook to ConsolePage.vue to set this.$refs.consoleDisplayer.autoScroll = this.autoScrollEnabled;.

Accessing localStorage can throw an error if it is disabled or restricted. Wrap the setItem call in a try-catch block to handle potential errors gracefully.

try {
  localStorage.setItem('console_auto_scroll', val);
} catch (e) {
  console.error('Failed to save auto-scroll state:', e);
}
