earnings summary CSV exports only first 2 decimal digits for token_value. Results in 0.00 ETH donations.

**Describe the bug**

The CSV export from https://gitcoin.co/settings/account#financials exports only the 2 decimals digits at token value. All digits should be exported.

Example entry

```

```

ETH amount should be `0.0005168` as per https://etherscan.io/tx/0x00298f72ad40167051e111e6dc2924de08cce7cf0ad00d04ad5a9e58426536a1
