- FlagSvg: remove redundant getDisplayFlagConfig call; config is already a
valid FlagConfig by type, so the validation/fallback was dead code. Also
replace the unreachable `?? "#adf661"` fallback with a non-null assertion.
- team/user models: pre-generate ID before insert so flagConfig is persisted
immediately on creation rather than relying on display-time generation.
- auth.server.ts: add create.after hook so BetterAuth-created users also get
a flagConfig written to the DB on signup.
