feat: add bilingual UI support and customize the web client experience

[danvei233]

Summary

This PR introduces a broader UI customization layer for Myrtille.Web, including bilingual support, a customized landing/login experience, popup localization, mobile keyboard support, and several interaction updates across the web client.

What Changed

Internationalization

• Added lightweight bilingual support for the main web page and popup dialogs.
• Default UI now supports both English and Simplified Chinese.
• Added a shared popup i18n script for common dialog translations.
• Localized multiple popup pages, including:
  • clipboard dialogs
  • file storage
  • share session
  • host edit/session dialogs
  • credentials prompt
  • password change
  • virtual/on-screen keyboard
  • generic dialog popup

Main Page Customization

• Reworked Default.aspx UI structure and text content.
• Updated branding from previous custom naming to Myrtille.
• Added a customized top bar and login presentation.
• Added a custom background asset for the login/landing experience.

Mobile Experience

• Added a mobile-only keyboard trigger in the top bar.
• Implemented a hidden textarea bridge to invoke the system keyboard on mobile browsers and forward input to the remote session.
• Adjusted mobile top-bar behavior to reduce conflicts with other actions.

Input and Interaction Changes

• Updated mouse/touch exclusion logic to avoid local UI clicks being forwarded to the remote session.
• Fixed popup close behavior that could unintentionally submit the main form and refresh the page.
• Adjusted toolbar toggle and popup interaction behavior.

Styling

• Customized Default.css extensively to match the new UI layout and branding.
• Added styling for the customized top bar, login area, popup shell behavior, mobile keyboard trigger, and range/button states.
• Added background.webp as a new visual asset.

Networking / Client Behavior Adjustments

• Updated several JS client modules under js/network, js/user, and related files to align with the customized UI behavior and interaction model.
• Touched configuration/audio/display-related scripts where needed to support the updated frontend flow.

Is there a plan to release the next major version, which is compatible with freerdp 3.0

[cedrozor]

Hi @zhongguo1987 yes, I'm finalizing a new release with it (with the latest FreeRDP version, I saw they just released 3.25.0). It's a massive update and I'm not 100% available for Myrtille, but it's coming! I will keep everyone informed and, as soon as I have more visibility for a release date, I will make announcements on the Myrtille forum

[zhongguo1987]

thank you ! Looking forward to your masterpiece
