5b2e4c4a88 log: update progress calculations for background validation (Pol Espinasa)
Pull request description:
`getblockchaininfo` returns `verificationprogress=1` and `initialblockdownload=false` even if there's background validation.
This PR adds information about background validation to rpc `getblockchaininfo` in a similar way to `validationprogress` does.
If assume utxo was used the output of a "sync" node performing background validation:
```
$ ./build/bin/bitcoin-cli getblockchaininfo
...
"mediantime": 1756933740,
"verificationprogress": 1,
"initialblockdownload": false,
"backgroundvalidation": {
"snapshotheight": 880000,
"blocks": 527589,
"bestblockhash": "0000000000000000002326308420fa5ccd28a9155217f4d1896ab443d84148fa",

"verificationprogress": 0.2815790617966284
},
"chainwork": "0000000000000000000000000000000000000000df97866c410b0302954919d2",
"size_on_disk": 61198817285,
...
```
If assume utxo was not used the progress is hidden:
```
$ ./build/bin/bitcoin-cli getblockchaininfo
...
"mediantime": 1756245700,
"verificationprogress": 1,
"initialblockdownload": false,
"chainwork": "00000000000000000000000000000000000000000000000000000656d6bb052b",
"size_on_disk": 3964972194,
...
```
The PR also updates the way we estimate the verification progress returning a 100% on the snapshot block and not on the tip as we will stop doing background validation when reaching it.
