Emails from iOS and MacOS clients can often come with size
transformation. This results in a broken layout when sanitizing with Vue
letter.
This PR updates the vue-letter to include the [recent changes made
there](https://github.com/mat-sz/vue-letter/pull/2). And adds the
`transform` and `transform-origin` properties to the allow list

Some emails contain HTML content within the text part, but our content
parser currently strips HTML automatically, which needs a proper fix. In
the new UI, the fallback for HTML content was set to the parsed content,
which may omit HTML tags, leading to issues like missing inline
attachments.
This PR updates the fallback mechanism to use the text content instead
of the parsed content, ensuring HTML elements are preserved.
Fixes
https://linear.app/chatwoot/issue/CW-4046/text-content-is-not-respected-in-emails
This PR has fixes for the following issues
- Inconsistent spacing between meta and text in text bubble
- Activity bubble overflows for longer text (for now I have truncated
it, I'll work with @absurdiya on a better solution)
- Ugly lookinh gradient for expand button on email bubble
- Email bubble overflow issues and text rendering issues
- Alignment for error message
- Minute-wise grouping not working
- Link color should not be blue
- Use `gray-3` for bubble background instead of `gray-4`
To test this, set the `useNextBubble` value to `true` in the
localstorage. Here's a quick command to run in the console
```js
localStorage.setItem('useNextBubble', true)
```
```js
localStorage.setItem('useNextBubble', false)
```
