feat(frontend): komponenty panelu

Widok rozbity na komponenty odpowiadające kafelkom pulpitu:

- AppHeader, VoiceChannelPanel, PlayerPanel, AddTrackPanel
- UploadsPanel wraz z UploadedFileRow współdzielonym z oknem modalnym
- QueuePanel i QueueItem - przeciąganie, zmiana kolejności, limit odtworzeń
- HistoryPanel, ModalShell, SettingsModal, UploadsLibraryModal, ToastHost

Arkusz stylów przeniesiony ze static/style.css bez zmian w wyglądzie.
Style, które app.js wstrzykiwał inline przy budowaniu HTML-a, przeniesione
do klas współdzielonych i bloków scoped w komponentach.

Poprawki bezpieczeństwa wynikające z przepisania:

- Tytuły utworów i nazwy plików nie trafiają już do innerHTML. Poprzednia
  wersja składała wiersze kolejki, historii i listy plików ze stringów,
  więc tytuł zawierający znaczniki HTML był wstawiany do DOM bez escapowania.
- Nazwy plików nie są już wklejane do atrybutów onclick z ręcznym
  escapowaniem apostrofu, które i tak nie obejmowało cudzysłowu. Zdarzenia
  podpina Vue, bez generowania kodu w stringach.
