Add upload type chooser and redesign upload modal

Clicking Create now opens a card-based chooser (Generic / Music / Sports)
before the upload modal; the chosen type is applied and its Content Type
dropdown is hidden as redundant.

Per type:
- Generic/Match show their fields inline in the modal (no card/popup);
  Music keeps the track-card + Track Editor popup for multi-language tracks.
- "Language Track" wording stays music-only; a single Language field is now
  available for generic/match too (mirrored on the mobile create page with
  name-swapping so only the active picker submits).

Also unifies all modal controls (dropdowns, selects, inputs) to one larger,
red-accented dark style scoped to #uploadModal.
