Bridge / DEX config onchain

### Is your feature request related to a problem?

### Describe the solution you'd like

The relation between UCIds and token addresses for each environment is configured in a json file in the project.
When we want to add new tokens, we need to recompile the project and update dependencies.
The goal of this issue is to move onchain the configuration ```/lib/src/domain/repositories/tokens/ucids_tokens.json```

No need to define all networks in the same config
Distinct config for each network.

So, instead of
```
{
"mainnet": {
"0000457EACA7FBAA96DB4A8D506A0B69684F546166FBF3C55391B1461907EFA58EAF": 1027,

}
}
```

Create in each network a transaction chain with data txn
```
{
"ucids": {
"00001A4AB7AD0CE2B494C965C66FF2962692A5FE5ECB71B345ABB53BAD88A83A01F1": 3890,
"00003DF600E329199BF3EE8FBE2B8223413D70BCDD97E15089E6A74D94DE3F1173B4": 1027,
"0000288BF6F0E12457B125DC54D2DFA4EB010BE3073CF02E10FB79B696180F55B827": 1839,
"0000353AF3AF4BC3CB70E16A5DA4F5A842140C8FE63314E9B7336089C973821B544F": 1027
}
}
```

We can follow the example of verified tokens available in these tx chains

### Additional context

Remove coin's name from `CryptoPrice` class

### Epic

_No response_

Start by reading /lib/src/domain/repositories/tokens/ucids_tokens.json and locating the CryptoPrice class. Inspect the linked verified-token transaction chains to understand the proposed onchain data format and network separation. Done means token mappings can be updated onchain without recompiling and the coin name is removed from CryptoPrice.
