Wrap last column to terminal width in CLI table formatter

[Copilot]

Description

When CLI commands like rad resource-type show render tables with long values (e.g., property descriptions), the output previously broke mid-word at the terminal edge, producing misaligned and hard-to-read output. This PR replaces the text/tabwriter-based renderer with a custom line-by-line renderer that detects the terminal width and intelligently word-wraps the last column, padding continuation lines so columns stay aligned.

Before: A long description wraps mid-word at the terminal boundary, breaking alignment:

size         string    false     false      The size of the PostgreSQL database, non production environments can be (S)
mall or (M)edium, production environments can be or (S)mall, (M)edium, (L)arge, or (XL)arge

After: The last column wraps on word boundaries and continuation lines are padded to stay aligned:

size         string    false     false      The size of the PostgreSQL database, non production
                                            environments can be (S)mall or (M)edium, production
                                            environments can be or (S)mall, (M)edium, (L)arge,
                                            or (XL)arge

Key implementation details:

• Terminal width is detected via golang.org/x/term; when output is piped (width unknown), no wrapping is applied.
• All column-width and padding calculations use utf8.RuneCountInString so multi-byte UTF-8 content stays aligned.
• Long unbreakable words (e.g., URLs) are split on rune boundaries, never inside a UTF-8 sequence.
• Internal whitespace within cells is preserved; only trailing whitespace at wrap boundaries is dropped.

Type of change

• This pull request fixes a bug in Radius and has an approved issue (issue link required).

Pull request overview

This PR fixes misaligned CLI table output by replacing the text/tabwriter-based table renderer with a custom renderer that can word-wrap the last column to the detected terminal width, keeping continuation lines aligned under the correct column.

Changes:

• Replaced the table output implementation with a manual renderer that computes column widths and wraps the last column when terminal width is known.
• Added tests validating last-column wrapping behavior (including unbreakable tokens) and no-wrap behavior when terminal width is unknown.
• Promoted golang.org/x/term (and github.com/hashicorp/go-version) to direct dependencies in go.mod.
