chain call functions dayjs、tz、hour、minute return incorrectly

**Describe the bug**
```
const d1 = dayjs('2024-04-09T22:30:50Z').tz("UTC").hour(10).minute(10).format() // '2024-04-09T10:10:50Z'
const value1 = dayjs('2024-04-09T22:30:50Z').tz("UTC").hour(10).minute(10).valueOf() // 1712686250000
const d2 = dayjs(1712686250000).tz("UTC").format() // '2024-04-09T18:10:50Z'

```

**Expected behavior**
excepte d1 === d2

**Information**
- Day.js Version 1.11.10
- OS: MacOs
- Browser : chrome 版本 123.0.6312.107（正式版本） (arm64)
- Time zone: Asia/Shanghai

Start by reproducing the provided dayjs, tz, hour, minute, format, and valueOf chain in a local test. Trace the timezone-related implementation and existing tests to determine why the formatted value and timestamp disagree; done means d1 and d2 produce the same instant and the regression is covered by a test.
