Disable dashboard i18n in Django settings

[Copilot]

With all non-English locale files removed, disables Django's internationalization system for the dashboard by changing configuration instead of modifying templates.

Changes

Settings (readthedocs/settings/base.py)

• Set USE_I18N = False to disable internationalization
• Reduced LANGUAGES tuple to only English
• Disabled django.middleware.locale.LocaleMiddleware
• Disabled django.template.context_processors.i18n

URLs (readthedocs/urls.py)

• Disabled i18n URL patterns (/i18n/)

Transifex Configuration

• Removed .tx/config for dashboard translations

Locale Files

• Removed all non-English locale directories (26 languages)
• Kept only readthedocs/locale/en/

Templates

• Dashboard templates retain original i18n tags ({% trans %}, {% blocktrans %})
• Tags become no-ops when USE_I18N=False

Rationale

Disabling i18n at the framework level provides several benefits:

• Eliminates translation lookup overhead
• Maintains template code standards for future maintainability
• Removes unnecessary middleware and context processor processing
• Makes future re-enablement easier if needed

The templates remain unchanged with standard Django i18n patterns, but Django won't process them since USE_I18N=False.

Original prompt

Remove dashboard locale data, since our next ext theme is not translated.

@copilot remove all the translated locale files, don't touch the templates.

@copilot remove all the translated locale files, don't touch the templates.

Done. Reverted the template changes and removed all non-English locale directories. Only readthedocs/locale/en/ remains. The changes are in commit e9b4437.

@copilot Remove any transifex config and other invoke tasks that update these files as well.

@copilot Remove any transifex config and other invoke tasks that update these files as well.

Removed .tx/config (transifex configuration for dashboard translations) in commit 2d3438e. The l10n invoke tasks in tasks.py are for documentation translations only (work in docs/ directory), not dashboard locale files, so they remain unchanged.

@copilot dont touch the templates but do change settings, etc.

@copilot dont touch the templates but do change settings, etc.

Done. Reverted template changes and disabled i18n in settings instead. Changes in commit 9bd57fe:

• Set USE_I18N = False in readthedocs/settings/base.py
• Reduced LANGUAGES to only English
• Disabled LocaleMiddleware and i18n context processor
• Disabled i18n URL patterns in readthedocs/urls.py

Templates now retain their i18n tags, but Django won't process them since USE_I18N=False.

Not sure if this will effect anything (eg. emails? notifications?), but if the dashboard isn't translated, I think this is the right move to rip the infra out.

[agjohnson]

Removing the translation files seems like the wrong approach here.

What we need is to ensure translation source strings are updated from the templates. This hasn't been set up yet and there are likely some extra steps here. Or it might just be a matter of source strings being out of date. But ultimately the source strings should probably still be in the locale files in this repo, I'm guessing. If not, and we translate at ext-theme, we still need these files to enable application translations and translation of source strings in the code here.
