Phase 15: language + bias als Spalten, Filter, Edit-Form

Bisher waren die DB-Felder sources.language und sources.bias zwar gepflegt
(254/275 Quellen mit bias, 254 mit language), aber in der Verwaltung nicht
sichtbar. Der Admin konnte nicht filtern oder editieren.

Backend (routers/sources.py)
- GlobalSourceCreate + GlobalSourceUpdate Pydantic-Modelle: language +
  bias als Optional[str] erweitert (max 100 / 500 Zeichen).
- SOURCE_UPDATE_COLUMNS: language + bias hinzu.
- INSERT in create_global_source: schreibt language + bias mit.
- Neuer Endpoint GET /api/sources/global/languages: distinct language-Werte
  fuer Frontend-Filter-Dropdown.

Frontend HTML (dashboard.html)
- Grundquellen-Filter-Bar: Sprachen-Dropdown ergaenzt.
- Grundquellen-Tabellenkopf: 2 neue Spalten Sprache (sortable) + Bias.
- modalSource: 2 neue Felder language (mit datalist Vorschlaegen) + bias.
- Kundenquellen-Filter-Bar: Sprachen-Dropdown.
- Kundenquellen-Tabellenkopf: Sprache (sortable) + Bias.

Frontend JS (sources.js)
- loadGlobalSources lädt /languages parallel zu /global + /global/stats,
  populiert beide Sprache-Dropdowns + datalist im Edit-Modal.
- renderGlobalSources: cols 11 -> 13, language+bias-Zellen
  (Bias mit Tooltip fuer Lang-Texte).
- filterGlobalSources: Sprache-Filter, Bias in Suche.
- editGlobalSource: language + bias laden.
- Form-Submit: language + bias mitgesendet.
- renderTenantSources: cols 8 -> 10, language+bias-Zellen.
- tenantFilters um language erweitert, applyTenantFilterAndSort prueft.

Cache-Buster ?v=20260509 (heute) bleibt - Tag wechselt erst morgen.
