fix(rpc): adding namespaces back

[lumtis]

Description

Adding debug methods along with other RPC back given the fact that it can be configured in the node config.

@CharlieMc0 do you know if a specific method in a namespace can be disabled in the node config?
We wanted to disable the method from eth namespace:

SendTransaction
Sign
SignTypedData

because those interact with unlocked accounts in the node and therefore have some security concerns.

Closes: #1219

Only the namespace can be disabled, not specific methods. It might be okay to keep those methods disabled.

SendTransaction
Sign
SignTypedData

The only complaints we got were around debug.

Ok, it makes sense to me, the three methods looks for niche purposes to me.
