chore(config): update system and application configurations

- **Alacritty**:
  - Update font family from `DejaVuSansM Nerd Font Mono` to `DejaVu Sans Code`.

- **i3 Window Manager**:
  - Remove unused `poweroff` binding (`+Shift+s`).

- **Ranger**:
  - Update bookmark paths for streamlined navigation.

- **SSH Configuration**:
  - Remove obsolete hosts (`docker-02`).
  - Add new entries for `docker-host00` and `docker-host01` with `ProxyJump` through `aya01`.
  - Correct `git.tudattr.dev` hostname mapping from `192.168.20.19` to `192.168.20.34`.

- **Vim Spell Check**:
  - Add `CCS` to the custom spell file.

These changes optimize user workflows, improve configuration accuracy, and update mappings for SSH and application environments.
