Feature: Add configurable remote-desktop quality levels menu

Add an "高级 (Advanced)" menu after "其他 (Other)" whose
"远程桌面质量等级 (Remote Desktop Quality Levels)" item opens a dialog to
edit the six preset QualityProfile levels (max FPS, max width, codec
algorithm, bitrate). The dialog edits a working copy in a full grid with
per-field validation and a restore-defaults button; on OK it persists the
values to the [quality] INI section.

The server stays authoritative: LoadQualityProfilesFromCfg loads the saved
levels at startup (falling back to GetQualityProfile defaults), and
ScreenSpyDlg now sends CMD_QUALITY_PROFILES from GetQualityProfileCfg so
new remote-desktop sessions transmit with the configured parameters. Added
en_US/de_DE/zh_TW translations for the menu and dialog strings.
