Add global quiet and verbose flags

[cnaples79]

Summary

• add global CLI quiet/verbose flags so users can choose errors-only or more detailed output
• wire verbosity into logging and display helpers to suppress non-error prints when quiet is enabled

Changes

• introduce -q/--quiet and counted -v/--verbose flags (with -V for version) at the root Typer app
• configure logging levels based on flags and pass settings to display utilities
• update display utilities to honor quiet mode and disable progress output when quiet

Fixes #5

Thanks @cnaples79 for this contribution!

Clean implementation of verbosity flags. The change from -v to -V for version is a good practice.

Merged! If you want to contribute more, there are other interesting issues labeled "good first issue".
