[ESLint 7/10] Fix i18next/no-literal-string warnings

[ShaileshParmar11]

Fixes #30985. Part of epic #30977.

Stacked PR 7 of 10 — base branch ShaileshParmar11/eslint-06-duplicate-string. Review after the previous PR in the stack. The diff here contains only the i18next/no-literal-string changes.

⚠️ Stacked, not independent — this PR merges after #the one below it in the stack; GitHub auto-retargets the base to main as each lands. See epic #30977 for the full approach and reviewer caveats.

Behavior-preserving lint cleanup. Verified: target rule(s) → 0, no new warnings (git-stash ESLint before/after), 0 new tsc signatures vs baseline.

Reviewer notes — the i18n approach

98% (2,242) of the i18next/no-literal-string warnings were in test/spec/mock files, which contain no user-facing strings. Rather than 2,242 inline disables, the rule is turned off for test/spec/mock files via the existing test-file override in eslint.config.mjs — one config line (trivially reversible). The 40 genuine production strings are properly internationalised with t() + 26 new alphabetically-sorted en-us.json keys; yarn i18n then synced all 20 locale files. ⚠️ The 26 keys land as English placeholders in the 19 non-English locales — real translation is unavoidable human follow-up (CI only verifies key sync, which passes).

❌ PR checklist incomplete

This PR cannot be merged until the following are addressed on its linked issue:

• No GitHub issue is linked. Link an issue in the Development section of the PR (or add Fixes #12345 to the description). For a same-org cross-repo issue, add Fixes open-metadata/<repo>#123 to the description.

The fields live on the linked issue in the Shipping project (open the issue → right sidebar → Projects). After you set them, re-run this check (or push a commit) — issue/project changes do not re-trigger it automatically.

Maintainers can bypass this check by adding the skip-pr-checks label.

Superseded by #31031. This PR was auto-closed by GitHub during a stack reorder (its head branch became an ancestor of its old base, so GitHub marked it "merged" — nothing actually merged into main). The i18n changes now live in #31031 with the correct base. Please review there.
