## Description
This PR changes to translation to properly handle different content
types during translation.
### Changes
1. **Email translation with HTML support**
- Properly detects and preserves HTML content from emails
- Sets `mime_type` to 'text/html' when HTML content is present
2. **Email translation with plain text support**
- Falls back to email text content when HTML is not available
- Sets `mime_type` to 'text/plain' when HTML is not available and
content type includes 'text/plain'
3. **Plain message with plain text support (Non email channels)**
- Sets `mime_type` to 'text/plain' for non-email channels
- Fixes an issue where Markdown formatting was being lost due to
incorrect `mime_type`
**Note**: Translation for very long emails is not currently supported.

Previously, viewing translations required opening a modal, which was a
frustrating experience. This update improves the UX by displaying
translations inline.

A sample message with translated content (which has an option to see the
original):
<img width="313" alt="Screenshot 2025-03-12 at 6 57 49 PM"

Right now, the translation is done based on the account locale. Some of
the future considerations.
- Add personal preference for the language (For eg: an agent can use the
software in spanish even though the company default is english), then
support translations based on personal preference.
- Add support for LLM translations (OpenAI integration)
- Add translations if Captain is enabled
- Add auto translation if the feature is turned on.
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)
```
