Ekaterina Pavlova 119ca27994 blockfetcher: fix block enqueue logic
Previously, the `blockQueuer` routine, which enqueues blocks into
`bQueue`, could be blocked on enqueing newer blocks if older blocks
downloading is delayed by NeoFS.

The `blocksCh` channel, acting as a queue ordered by download speed,
conflicted with the BQueue requirement for strict sequential enqueuing
(expecting an exact range of blocks), resulting in a deadlock that
stalled the process.

Before with default config settings:
```
2024-11-27T17:12:19.348+0300	INFO	persisted to disk	{"blocks":
 0, "keys": 116, "headerHeight": 0, "blockHeight": 0, "took": "15
 .509083ms"}
2024-11-27T17:19:39.574+0300	INFO	persisted to disk	{"blocks":
 16, "keys": 11107, "headerHeight": 216768, "blockHeight": 216768,
 "took": "62.762041ms"}
```
Average block persistence speed: 492.40 block/s
Average blocks number for each persist log: 584.28

After:

```

 "took": "52.43925ms"}
```
Average block persistence speed: 610.33 block/s
Average blocks number for each persist log: 752.61
