Statusline progress bar gets a visual refresh for at-a-glance readability

The progress bar on the terminal statusline is now much easier to read. We've switched the characters to clearer solid and hollow squares ("■□"), and moved from standard ANSI colors to a high-contrast 256-color palette (teal, orange, and dark red). Now, you can instantly tell if your usage is in a safe, warning, or danger state with just a quick glance. It's like upgrading a dim traffic light to ultra-bright LEDs—you know exactly when to hit the brakes from a mile away. We've also updated the Traditional Chinese panel screenshot in the documentation to reflect the latest UI changes.

Original changelog

Original changelogStatusline progress bar gets a visual refresh for at-a-glance readability

**Statusline progress bar visual refresh**: progress bar characters switched from `█░` to `■□` (filled / hollow squares), and the color palette moved from standard ANSI green/yellow/red (32/33/31) to 256-color teal/orange/dark-red (42/214/160) for stronger contrast around the 50% threshold — safe / warning / danger states are now distinguishable at a glance. Changes confined to `usage_statusline.py` (`progress_bar()` and `color_by_pct()`); HTML reports and the TUI progress bars are unaffected.
**Traditional Chinese default panel screenshot refreshed**: `docs/繁體中文面板.png` updated to reflect the latest UI (new "Report / Terminal" toggle, per-project cost display, footer attribution).
