Make sure the queries return proper Response Structs instead of naked values

[kerber0x]

Go through all the contracts and make sure the queries are returning proper Response structs, such as

#[cw_serde]
#[derive(QueryResponses)]
pub enum QueryMsg {
    /// Returns the amount of tokens that have been bonded by the specified address.
    #[returns(BondedResponse)]
    Bonded { address: String },
}


#[cw_serde]
pub struct BondedResponse {
    pub bonded: Uint128,
}

vs

#[cw_serde]
#[derive(QueryResponses)]
pub enum QueryMsg {
    /// Returns the amount of tokens that have been bonded by the specified address.
    #[returns(Uint128)]
    Bonded { address: String },
}

Note that the changes could break things for the front ends, so make sure to coordinate with the respective teams before migrating the contracts.

P.S.:
The only exception can be the Config struct.
