 * Resolve the name to show for a spot listing — the spot counterpart of
 * `toDisplaySymbol`, with the same precedence and the same sanitization.
 *
 * Precedence: curated override (`TOKEN_SYMBOL_OVERRIDES`, already applied by
 * the caller via `normalizeTokenSymbol`, detected as `displaySymbol !== name`)
 * → the token's live `setTokenAnnotation` display name → the curated/clean
 * symbol itself. The result is always a non-empty string.
 *
 * A live annotation that is not a plausible market name is refused and the
 * symbol is used instead — see `toValidDisplay` in `to-display-symbol.ts`.
 * Curated overrides skip that check because we write them.
