[i3+sway] Replace i3status with i3blocks to replicate waybar

Created i3blocks configuration with modules matching waybar setup including disk, CPU, memory, pulseaudio, backlight, network, battery, and clock. Applied matching color scheme and workspace button styling. i3blocks works with i3wm unlike waybar which only supports sway.
