fix(formatters): expand streaming table to fill terminal width

[betegon]

PRE:

POST:

Summary

The sentry logs --follow streaming table rendered ~72 columns wide even on wide terminals. The Message column wrapped unnecessarily despite ample space.

fitColumns only shrinks columns — when hint rows (short placeholder data) produce intrinsic widths below the terminal width, it returns them as-is with no expansion. After fitColumns, the StreamingTable constructor now expands the last column to absorb remaining space. renderTextTable is unaffected since it uses real data.

Test plan

• bun test test/lib/formatters/text-table.test.ts — 32 tests pass
• bun test test/lib/formatters/log.test.ts — 34 tests pass
• Manual: sentry logs --follow fills terminal width
• Manual: sentry issue list table unaffected
