📄 Description

Summary

This PR adds internationalization (i18n) support for the embedded IdP login page, with Chinese (zh-CN) translations included.

Previously, all login page text was hardcoded in English. Users deploying NetBird for Chinese-speaking teams had no way to localize the login experience.

Changes

1. Template i18n (`idp/dex/web/templates/`)

login.html and password.html: Replaced hardcoded English text with {{ .Extra.xxx }} template variables with English fallbacks
All existing deployments continue to work unchanged (fallback to English)

2. Frontend config (`idp/dex/config.go`)

Added Locale field to Frontend struct
Added FrontendI18n struct and GetI18n() function
Added ToExtraMap() helper to convert translations to template Extra map
ToServerConfig() merges locale-based translations into the Extra map

3. Translations included

zh-CN: Full Chinese translations for all login page strings

How to use

frontend:
  issuer: "NetBird"
  theme: "light"
  locale: "zh-CN"  # Add this line

Or programmatically:

config.Frontend.Locale = "zh-CN"

Screenshots

Before (English):

"Sign in" / "Enter your credentials" / "Email Address" / "Password"

After (zh-CN):

"登录" / "请输入您的凭据" / "邮箱地址" / "密码"

Backward Compatibility

If locale is not set or empty, all templates fall back to the original English text
The Extra map can still be used for custom overrides, which take precedence over locale translations

Summary by CodeRabbit

New Features
- Added locale-based translations for login page text.
- Added configurable labels for connector buttons, sign-in headings, form fields, validation messages, submit actions, and navigation links.
- Added fallback text so existing login behavior remains unchanged when translations are unavailable.
- Added frontend locale configuration support for selecting translated content.
