fix: resolve i18n no-restricted-imports lint warnings (#8704)

## Summary

Fix all i18n `no-restricted-imports` lint warnings and upgrade rules
from `warn` to `error`.

## Changes

- **What**: Migrate Vue components from `import { t/d } from '@/i18n'`
to `const { t } = useI18n()`. Migrate non-component `.ts` files from
`useI18n()` to `import { t/d } from '@/i18n'`. Allow `st` import from
`@/i18n` in Vue components (it wraps `te`/`t` for safe fallback
translation). Remove `@deprecated` tag from `i18n.ts` global exports
(still used by `st` and non-component code). Upgrade both lint rules
from `warn` to `error`.

## Review Focus

- The `st` helper is intentionally excluded from the Vue component
restriction since it provides safe fallback translation needed for
custom node definitions.

Fixes #8701
