Add a single getUserDisplayName(user) function to app/models/user.ts that
encapsulates the username → displayName fallback logic. Replace 9 scattered
inline expressions across the codebase (owner-map, scoring-calculator,
league routes, settings, invite flow, draft API, Clerk webhook) with calls
to the shared helper.
No behaviour change — all existing logic preserved, just centralised.

Adds GET /api/seasons/:seasonId/draft returning current pick number,
who's on the clock, and the full picks list with usernames and sport.
