Sync data between the backends and reset first_seen date

We might have hit again some variation of #40018 in relay-search#40024 (closed).

I have checked and it seems the two backend don't have the same data. For some delay in getting the consensus from collector at the right time, most of relays on onionoo-backend-02 got the first_seen date reset. The same happened on onionoo-backend-01 but for a smaller fractions of node.

The plan is to copy over the data from onionoo-backend-01 to onionoo-backend-02 and reset the first_seen date for these relays with info we have between the uptime field and the bandwidth history data.
