Replace heredoc boot scripts with printf one-liners for mobile copy-paste reliability

Browse Source 
Heredocs fail silently on Android Termux when copy-pasting from the admin GUI
(trailing whitespace from clipboard prevents EOF recognition). Switched to
printf commands in both the setup wizard and MkDocs docs. Also added
source ~/.bashrc and boot script steps directly in the wizard Step 4.

!!! warning "Replace YOUR_KEY_HERE"
Edit the script and replace `YOUR_KEY_HERE` with your actual API key. Or if you've already saved it in `~/.bashrc`, replace the export line with `source ~/.bashrc`.
!!! tip "Why printf instead of heredoc?"
Heredoc (`<< 'EOF'`) blocks are unreliable when copy-pasting on mobile devices — trailing whitespace or clipboard quirks prevent the `EOF` from being recognized. The `printf` one-liner is more reliable for mobile copy-paste.
