*: 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.

state: optimize NEP17Transfer struct
...
We have both from and to here, so technically we can either drop the neg/neg
trick from the processTokenTransfer() or drop one field from the structure
(the other side is a part of the key). Drop the field since this can make the
DB a bit more compact. Change Amount to be a pointer along the way since
that's the "native" thing for big.Int, we've used non-pointer field
specifically to avoid Neg/Neg problems, but it looks like this is not
necessary.
This structure is only used by the RPC server and I doubt anyone uses it via
the *Blockchain.

Packages like core/state or core/mpt shouldn't import whole core/storage just

core, rpc: use Seek to iterate over NEP* transfers
...
The results are controversial a bit. MemoryPS is a special storage
and the new approach doesn't help it to iterate through NEP17 transfers.
However, on long distances (if transfers are requested for more than
1000 blocks, which is ~4.1 hours of mainnet chain) both LevelDB and
BoltDB perform good enough with the new approach. Taking into account
the fact that default value for the query period of `getnep17transfers`
RPC handler is a week (~40K mainnet blocks) we can sacrifice MemoryPS
performance in favour of BoltDB and LevelDB optimisation.
Close #2263 .

*: use NEP-XX naming consistently in docs/comments

Standards are NEP-11 and NEP-17, not NEP11, not NEP17, not anything
else. Variable/function names of course can use whatever fits, but documents
and comments should be consistent wrt this.
