Eliminated the manual `formatPageText` function that previously rendered
pagination text (e.g. “第 {{start}} - {{end}} 条，共 {{total}} 条”) in each
Table. Pagination now relies on the default Semi UI text or the global
i18n configuration, reducing duplication and making future language
updates centralized.
Why
---
* Keeps table components cleaner and more maintainable.
* Ensures pagination text automatically respects the app-wide i18n
settings without per-component overrides.
