config: cleanup, update flake

Packages:-

bcachefs-tools: nixpkgs -> upstream
hyprland-portal: override to get the latest version
vesktop: nixpkgs -> flatpak
vim -> neovim
++ bat
++ tree

Hardware:-

zram: size 50 -> 200: this increases compression level
to increase the usable zram, this does not mean actual
memory used

swaps: disable vm.dirty_background_ratio
This is because increasing this actually caches more data
into RAM during IO, which can crash system by OOM

Services:-

gnome-keyring: configure gnome-keyring PAM to unlock with
gdm-password

boot-modules: load AMDGPU at stage-1 boot
console: allow support for mouse in tty

Cleanup:-
move containers module to system, enable it conditionally
disabled currently
use hypridle and hyprlock module
