feat: Update translated content inline (#11074)

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"
src="https://github.com/user-attachments/assets/52434086-b57f-40e8-87b8-314c3519df4b"
/>

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.
