Add friendly media source names with brand icons

- Registry of 17 popular media apps (browsers, players, streaming)
- Substring matching resolves raw process names to friendly names
- Brand-colored SVG icons displayed inline next to source name
- Russian locale support for Yandex Music (Яндекс Музыка)
- Unknown sources fall back to .exe-stripped name
