Subject: [PATCH] feat: auto-detect Console width (#3327)

# What does this PR do?
<!-- Provide a short summary of what this PR does and why. Link to
relevant issues if applicable. -->
Addresses Issue #3271 - "Starting LLS server locally on a terminal with
120 chars width results in an output with empty lines".

This removes the specific 150-character width limit specified for the
Console, and will now auto-detect the terminal width instead. Now the
formatting of Console output is consistent across different sizes of
terminal windows.

<!-- If resolving an issue, uncomment and update the line below -->
<!-- Closes #[issue-number] -->
Closes #3271

## Test Plan
<!-- Describe the tests you ran to verify your changes with result
summaries. *Provide clear instructions so the plan can be easily
re-executed.* -->
Launching the server with several different sizes of terminal windows
results in Console output without unexpected spacing. e.g. `python -m
llama_stack.core.server.server /tmp/run.yaml --port 8321`
