Update flake.lock and refine module settings

Bump revisions, hashes and timestamps in flake.lock for several inputs.

Simplify greetd configuration by using a direct default_session
assignment.
Restructure core stylix targets, adding a kmscon placeholder and
reorganizing limine options.
Remove empty GTK4 theme block, keeping only the dark‑theme flag in extra
config.
Extend home stylix: enable librewolf with extra options and add a GTK
target with colors, fonts, and flatpak support.
