Create API crate and organize protobuf files

[georgi-l95]

Description

This PR fixes the rock-node-protobufs crate so it builds successfully again.
While compiling, several tonic::include_proto! paths referred to modules that are not generated by tonic-build, which produced “couldn’t read … No such file or directory” errors.
The change:

• Adds every missing (actually-generated) protobuf module under the com.hedera.* hierarchy.
• Removes / reorganises the stale module stubs that pointed to non-existent files.
• Enables #![allow(non_camel_case_types)] at crate root to silence harmless naming warnings emitted by generated code.

With these updates the protobuf crate now compiles its full set of 193 .proto definitions without errors.
