* Fix mobile league settings: prevent sports scroll and remove completion checkmarks
- Add overflow-hidden to sport label text span so flex truncation is properly contained
- Add min-w-0 to SettingsSection header inner flex item to prevent title/description overflow
- Remove completion check marks from mobile grid nav buttons (league settings has no completion concept)
- Remove "X of Y set" counter from mobile nav header
- Remove isComplete field from SettingsGridSection type and all data

* Fix race window in user creation and restore FlagSvg safety fallback
auth.server.ts: switch generateId to application-generated UUIDs so the
ID is known before the insert, then move flagConfig assignment from
create.after (a separate UPDATE) to create.before so it lands in the
initial INSERT with no race window.
FlagSvg.tsx: validate the config with parseFlagConfig before rendering;
corrupt or missing data falls back to a neutral gray triband flag rather
than silently rendering blank SVG shapes.
