i18n: complete Japanese translation for ja.ts (#17042)

## What

The Japanese locale (`web/src/locales/ja.ts`) was missing translations
for **1703 of 2686 keys (~63%)**. Because i18next's `fallbackLng`
silently falls back to English for any missing key, most of the UI
stayed in English even after selecting 日本語 — e.g. the Settings > Model
Providers page, the Agent/Flow builder, dataset configuration panels,
and more.

This PR fills in all 1703 missing keys with Japanese translations.
