- UI display: display_name first (#14358)

* - UI display: display_name first
  - Fallback: name
  - Technical identity: still name

  ### What changed

  - Added account display helpers and display_name state in user model:
      - flutter/lib/models/user_model.dart:16
  - Account/logout label now uses display_name (@name) when both exist:
      - flutter/lib/mobile/pages/settings_page.dart:689
      - flutter/lib/desktop/pages/desktop_setting_page.dart:2016
      - flutter/lib/desktop/pages/desktop_setting_page.dart:2135
  - Desktop Account info now shows both when applicable:
      - Display Name: ...
      - Username: ...
      - flutter/lib/desktop/pages/desktop_setting_page.dart:2039
  - Previously done group-list behavior remains:
      - group user list displays display_name with name fallback
      - flutter/lib/common/widgets/my_group.dart:187
  - Persistence path for display_name remains enabled (including group cache/submodule field):
      - libs/hbb_common/src/config.rs:2347
  - src/client.rs:2630
  - LoginRequest.my_name now resolves as:
      1. OPTION_DISPLAY_NAME (manual override)
      2. user_info.display_name
      3. user_info.name
      4. OS username fallback

* 1. GUID key (...Uninstall\{GUID}) is MSI-native metadata generated by Windows Installer.
  2. Non-GUID key (...Uninstall\RustDesk) is explicitly written by RustDesk’s MSI compatibility component in res/msi/Package/Components/Regs.wxs:44, populated by preprocess.py --arp from .github/workflows/
     flutter-build.yml:262.

  So they were not using the same EstimatedSize logic:

  - MSI GUID key: MSI-calculated size (KB).
  - RustDesk key: custom script value from res/msi/preprocess.py:339 (previously bytes, now fixed to KB).

  That mismatch is exactly why you saw different sizes.

* improve display name handling

  - Append (@username) when multiple users share the same display name
  - Trim whitespace from display_name before comparison and display
  - Add missing translate() for Logout button on desktop
