feat: i18n for emails (#1442)

## Description

Support setting a document language that will control the language used
for sending emails to recipients. Additional work has been done to
convert all emails to using our i18n implementation so we can later add
controls for sending other kinds of emails in a users target language.

## Related Issue

N/A

## Changes Made

- Added `<Trans>` and `msg` macros to emails
- Introduced a new `renderEmailWithI18N` utility in the lib package
- Updated all emails to use the `<Tailwind>` component at the top level
due to rendering constraints
- Updated the `i18n.server.tsx` file to not use a top level await

## Testing Performed

- Configured document language and verified emails were sent in the
expected language
- Created a document from a template and verified that the templates
language was transferred to the document
