fix(shell): repair broken aliases, modernize, make bash/zsh + linux/mac portable

- drop hardcoded /home/tke/.http_proxy sourcing; both proxy installers
  (update_bashrc_proxy.sh #PROXY_A93JK2, install_proxy.sh
  #PROXY_BRIDGE_CONFIG) inject their own bashrc lines
- fix 'set $_Z_OWNER=' (set positional params instead of the variable)
- prefer zoxide over z.sh, load only one jumper instead of both
- dockertags: dead Docker Hub v1 API -> v2, handle library/ prefix
- rot13: handle uppercase
- ppxml: drop dead duplicate with typo'd xmllin command
- exa (unmaintained) -> eza, fallback lsd -> ls; single ll definition
- guard linux-only bits (locate -A, ntfsmount, usbguard, apt+fzf, mc)
  and optional tools with command -v; batcat support for ubuntu
- unsetproxy: grep -P is GNU-only, unset vars explicitly instead
- quote ${workdir:-$(pwd)} mounts; dedupe mv/cp/pip/python
- guard shopt autocd (macOS bash 3.2)
