* Fall back to displayName when username is null for Discord webhook
Users who sign up via OAuth (Google, GitHub, etc.) without setting a
Clerk username have a null `username` field but always have a `displayName`
(computed from firstName+lastName or email). Previously, `usernameByClerkId`
was filtered to only include users with a non-null username, causing those
owners to appear without any identifier in Discord standings messages
(e.g. "Liverpool def. Galatasaray" instead of "Liverpool def. Galatasaray (Madmike)").

* Extract getUserDisplayName helper and use consistently throughout
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.

* Fix N+1 user queries in league loader and settings loader
Add findUsersByClerkIds() batch function to the user model and replace two
separate Promise.all+findUserByClerkId loops (one for owners, one for
commissioners) with a single inArray query in both $leagueId.server.ts and
$leagueId.settings.tsx. The merged query covers both owner and commissioner
IDs in one round-trip.

* Fix N+1 user queries in buildOwnerMap
Replace the Promise.all+findUserByClerkId loop with a single
findUsersByClerkIds batch query, consistent with the league loader
and settings loader fixes.
