bug: missing manual `Debug` impl for `IpfsConfig` in `configs` crate (secret leakage)

[isSerge]

Problem

configs crate relies on manual Debug implementations to redact api keys for each config struct, however it's easy to forget.

For example IpfsConfig does not have it, instead it uses automatic derive, which creates secret leakage risk:

#[derive(Debug, Clone, Deserialize, Serialize)] <----- problem here
pub struct IpfsConfig {
    pub gateway: Url,
    #[serde(deserialize_with = "deserialize_auth_token")]
    pub auth_token: Option<String>,
}

Impact

Leaking a secret is critical

Expected behaviour

API key has to be redacted

Suggested fix

Introduce SecretString newtype that implements Debug printing "<REDACTED>" and use it by default for all config secrets, for example:

#[derive(Debug, Clone, Deserialize)]
pub struct IpfsConfig {
    pub gateway: Url,
    pub auth_token: Option<SecretString>,
}

Can remove manual Debug impl for CoinGeckoConfig, OneInchApi and TenderlyConfig completely
