fix: add missing EventsOffAll export to runtime templates (#4883)

* fix: add missing EventsOffAll export to runtime templates

The EventsOffAll function was implemented in the internal runtime
(desktop/events.js) and exported in the wrapper runtime files, but was
missing from the public runtime templates that are generated in user
projects. This caused a type mismatch where EventsOffAll was declared
in the TypeScript definition but the implementation was missing.

This commit adds the EventsOffAll export and type declaration to all
frontend framework templates:
- Common templates (generate/assets/common)
- React / React-TS
- Vue / Vue-TS
- Svelte / Svelte-TS
- Preact / Preact-TS
- Lit / Lit-TS
- Vanilla / Vanilla-TS

Fixes #4703

* docs: add EventsOffAll to runtime events documentation

Added EventsOffAll function documentation to both English and Chinese
versions of the runtime events reference.

The function was already implemented in Go (pkg/runtime/events.go) and
JavaScript (internal/frontend/runtime/desktop/events.js), but was missing
from the public documentation.
