Add Pipelines Show Command

[tanishgupta-db]

Changes

Adds databricks pipelines show <catalog.schema.table> command: shows a table's columns and sample data (or --output json). Runs SELECT * FROM <table> LIMIT n on a SQL warehouse. The warehouse is taken from --warehouse-id, DATABRICKS_WAREHOUSE_ID (env set), the workspace default, or picked.

Also adds renderStaticWithTruncation in tableview for detecting terminal width and rendering a formatted table

Why

Users want a quick look at the data and schema of a dataset quickly without leaving the terminal. Mirrors the Catalog Explorer "Sample Data" experience for the CLI. Lives under the pipelines command group.
