* fix(xueqiu/kline,earnings-date): format dates in Asia/Shanghai instead of UTC (#1465)

`xueqiu/kline` and `xueqiu/earnings-date` formatted bar timestamps with
`new Date(ts).toISOString().split('T')[0]`. That string is the UTC
calendar date, always one day earlier than the date xueqiu shows in its
UI (which is Beijing-aligned for every market). Issue #1465 reports
"5月10日跑的,5月8号的k线没有" because the May 8 China trading-day bar
was labeled 2026-05-07. Same off-by-one was present in `earnings-date.js`.

Routes both call sites through a new `formatChinaDate(ts)` helper in
`clis/xueqiu/utils.js` built on `toLocaleDateString('en-CA', { timeZone:
'Asia/Shanghai' })`. Verified live against SZ300136 and AAPL: both now
match the dates shown on xueqiu.com.

Tests: `clis/xueqiu/utils.test.js` (new) pins the Asia/Shanghai semantic
with 4 cases (China midnight, late-evening, 16:00 UTC day boundary, and
nullish input). `npx vitest run --project adapter clis/xueqiu/` 49/49,
`npx tsc --noEmit` clean, `npm run build` 815 entries unchanged shape.

Closes #1465

* fix(xueqiu): stabilize China date formatting
