chore: reformat ARB files to 4-space indent

[beastoin]

Summary

• Reapply 4-space indentation to all 48 ARB localization files using jq --indent 4
• These files were reverted to 2-space indent by recent commits (Apr 26-27) that were made without the pre-commit hook running

Context

The repo's scripts/pre-commit hook enforces 4-space indent on ARB files. Recent l10n contributions landed without this hook active, causing all ARB files to revert to 2-space formatting.

@aaravgarg @krushnarout — please make sure you have the pre-commit hook installed to keep the project standardized:

ln -s -f ../../scripts/pre-commit .git/hooks/pre-commit

Test plan

• Ran jq --indent 4 . <file> on all 49 ARB files (48 changed, 1 already compliant)
• No content changes — indent-only reformatting
• Unblocks PR fix(auth): unified auth+BYOK middleware replacing per-endpoint Depends #6946 rebase (eliminates ARB diff noise)

Greptile Summary

This PR reformats all 48 ARB localization files from 2-space to 4-space JSON indentation to match the enforcement policy in scripts/pre-commit. The change is purely cosmetic — the equal insertion/deletion counts (260,540 each) confirm no content was modified.

Confidence Score: 5/5

Safe to merge — purely cosmetic whitespace change with no logic or content modifications.

All 48 files show equal insertions and deletions (260,540 each), confirming this is a whitespace-only reformat from 2-space to 4-space indentation. The pre-commit hook in scripts/pre-commit explicitly enforces this standard via jq --indent 4. No ARB string values, keys, or metadata were altered.

No files require special attention.
