Fix: Verbose flag working by default on Artbox

[investor-uyah]

The Artbox command line tool produces lengthy, unnecessary logs by default during runtime i.e. without the use of the --verbose flag. It looks like this at the moment.

(artbox) ✔ ~/artbox [main|✚ 1] 
01:09 # echo "Are you ready to join Link and Zelda in fighting off this unprecedented threat to Hyrule?" > /tmp/artbox/text.md
 artbox speech from-text \
    --title artbox \
    --input-path /tmp/artbox/text.md \
    --output-path /tmp/artbox/speech.mp3 \
    --engine edge-tts

A fix should be implemented to have the tool operate normally. Logs should not be displayed except with the use of the --verbose flag. Also, logs should be designed to appear more helpful. For instance, a display message indicating the successful completion of the process and the name and location of the output file.
