1b83dc2476 *: improve for loop syntax
Mostly it's about Go 1.22+ syntax with ranging over integers, but it also
prefers ranging over slices where possible (it makes code a little better to
read).

Notice that we have a number of dangerous loops where slices are mutated
during loop execution, many of these can't be converted since we need proper
length evalutation at every iteration.

4c288720cd services: allow some slippage in TestNotary
1. Allow 1-block slippage for multisignature request block generation to
   ensure that PostPersist for fb's NVB-th block is properly finished.
2. Allow 1-block slippage before sent request checks to ensure that
   PostPersist for NVB fb's NVB-th block was finished and all
   stale mains were properly marked by Notary service.

Overall, this commits ports the approach of #3390 to the whole test.

Close #3366.

f95004ad83 services: fix race in TestNotary
Close #3366. Roll back the test structure to the one that it has before
d2a7162217. Add one extra block to ensure
that main transaction won't be finilized. Add NVB increment slippage to
avoid race between the first fallback acceptance and block acceptance.
Add NVB increment slippage to the rest of fallbacks for test structure
unification.

d2a7162217 notary: fix "Condition never satisfied" in Notary test, fix #2422
The theory is:
 * we add a block
 * it triggers notary
 * which can process the fallback before we're to setFinalizeWithError
 * it'll fail and require an additional block to enter, but it's never added
 * FAIL

The solution is:
 * always add an additional block, but treat the first fb specially

5bb7c6b715 services: update logs flush after services shutdown
Added sync logs for every service separately to provide the ability to
have a custom logger for each service. This commit makes the code follow
the zap usages rules: `Sync calls the underlying Core's Sync method,
flushing any buffered log entries. Applications should take care to
call Sync before exiting.`

7589733017 config: add a special Blockchain type to configure Blockchain
And include some node-specific configurations there with backwards
compatibility. Note that in the future we'll remove Ledger's
fields from the ProtocolConfiguration and it'll be possible to access them in
Blockchain directly (not via .Ledger).

The other option tried was using two configuration types separately, but that
incurs more changes to the codebase, single structure that behaves almost like
the old one is better for backwards compatibility.

Fixes #2676.

eeeb0f6f0e core: accept two-side channels for sub/unsub, read on unsub
Blockchain's notificationDispatcher sends events to channels and these
channels must be read from. Unfortunately, regular service shutdown procedure
does unsubscription first (outside of the read loop) and only then drains the
channel. While it waits for unsubscription request to be accepted
notificationDispatcher can try pushing more data into the same channel which
will lead to a deadlock. Reading in the same method solves this, any number of
events can be pushed until unsub channel accepts the data.
