Redesign flake outputs

[TureBentzin]

The nix flake now has individual build outputs for each submodule of the project and no longer "fakes" the behavior by just changing the default executable. A "traditional" tablo-full package that builds everything together and lets CMake handle dependencies still exists.

Pull request overview

This PR restructures the Nix/CMake packaging so individual Tablo components and libraries can be built as separate flake outputs, while preserving a combined tablo-full package.

Changes:

• Adds CMake build options for selectively enabling libraries and executables.
• Expands flake outputs for individual libraries, executables, Docker images, and a joined default package.
• Renames Methods to METHODS across networking code and removes the old TCTest target.

flake.nix:136

• Enabling both library subdirectories here makes the tablo-master output install libtabcrypt, libtabnet, and their headers in addition to the master binary, while the flake also exposes separate libtabcrypt/libtabnet outputs and joins them into tablo. That duplicates the same lib/ and include/ paths in multiple outputs and can make the joined default package collide; build only the master target against the separate library outputs instead.

            enableMaster = true;
            enableLibtabcrypt = true;
            enableLibtabnet = true;

This is so smooth!

Wow! This flake is so beautifully implemented!
Thank you :)
