[codex] page through sandbox list

[calavera]

Summary

• Page through tl sbx ls responses by following paginator tokens/links.
• Print sandbox rows as each response page is read instead of collecting all sandboxes in memory.
• Preserve status filtering, quiet mode, archived listing, and final counts while streaming output.

Root Cause

tl sbx ls --all only read the first list response, so sandboxes after the first API page were never displayed.

Validation

• rustfmt --edition 2024 --check crates/cli/src/commands/sbx/ls.rs
• cargo test -p tensorlake-cli commands::sbx::ls::tests
