## 🚪 Why?
### Problem
Untranslated strings were silently reaching production. Several UI
components rendered raw English literals without going through \`__()\`,
and 15+ strings used via \`__()\` had no entry in \`lang/es.json\`,
causing Spanish-locale users to see untranslated text. There was also no
automated safeguard to catch new regressions.
## 🔑 What?
### Changes
- Add \`tests/Feature/LocalizationTest.php\` with two test groups that
run in CI:
1. **PHP translation files** — verifies every key in \`lang/en/*.php\`
exists in the matching \`lang/es/*.php\` file
2. **Spanish JSON translations** — scans all \`.ts\`/\`.tsx\` files for
static \`__()\` calls and asserts each key exists in \`lang/es.json\`
- Wrap previously unwrapped literals in \`__()\` in `header.tsx`
(Github, Discord, Dashboard, Log in, Register), \`appearance.tsx\`
(Chart color scheme heading and color scheme labels), and
\`rule-builder.tsx\` (field config labels and operator labels at render
site)
- Add 15 missing Spanish translations to \`lang/es.json\`: Discord,
Chart color scheme, Choose the color palette for your charts, Blue,
Colorful, Neutral, Pink, Account Name, Bank Name, contains, equals,
greater than, is empty, is not empty, less than
## ✅ Verification
### Tests
- New test: `tests/Feature/LocalizationTest.php` — 2 tests, 4
assertions, all passing
- Runs automatically in CI via the existing `./vendor/bin/pest` job (no
CI config changes needed)
### Manual Verification
- `php artisan test --compact tests/Feature/LocalizationTest.php` →
`Tests: 2 passed (4 assertions)`
