feat(power): integrate tlp and add battery management functions

This commit introduces a complete battery management solution by integrating TLP into the setup scripts and providing convenient control functions in Zsh.

Key changes:
- Adds `eco-batt` and `full-batt` functions to `.zshrc` to allow the user to easily switch between battery-saving (80%) and full-charge (100%) modes.
- Modifies `modules/apps.sh` to automatically install the `tlp` package.
- Adds logic to `modules/apps.sh` to enable and start the `tlp.service` so that power management is active on boot.
- Updates the `zsh-help` function to include documentation for the new battery management commands.
