feat: localize data panels and add funding trends

[jackhai9]

The trading panel previously showed only a rounded settled funding rate, making it easy to mistake a tiny historical rate for the current quote. It now combines the current funding rate, reported settlement interval, countdown, and settled-history chart while preserving nonzero precision. Other Binance metrics gain timestamped mini charts and matching explanations.

Both data panels follow the page's Simplified Chinese or English locale. CMC uses compact metric names and a third interpretation column with explicit ratio definitions. Ordinary ratios use two decimals. Default desktop and narrow-screen layouts keep the panels separate while retaining saved positions.

Versions: trading data 1.2.0, CMC data 0.2.0. Install/update URLs are unchanged.

Validation:

• Full npm test on the rebased release commit: 2528/2528 passed.
• Both affected builds, generated syntax checks, lint:tests, lint:ui-copy, metadata/install URL checks, and exact preview-to-artifact comparison passed.
• Isolated Chromium panel position/presentation checks: 33/33 passed, with rendered Chinese/English, light/dark, desktop, and narrow-screen previews inspected.
• The earlier full local Chromium run was 605/606. Its remaining failure was the existing orderbook test helper calling pauseAt(pageNow + 100) after that timestamp had passed, before the scenario's settings-change assertion. The spec, helper, fixture, orderbook artifact, and package inputs were unchanged; this remains a recorded test-timing finding rather than a passing scenario.

Live Binance/Tampermonkey validation and verbatim native English label comparison remain separate from the offline evidence. The preview uses labelled example data and makes no external requests.
