(fix) Add missing English translation keys

[theluckystrike]

Changes

Four keys used in the dashboard are not in en.json or any other locale file, so i18next falls back to the raw key and users see text like alert.noCustomEventError:

• alert.noCustomEventError: validation message when a custom event alert has no event name (ProjectAlertsSettings.tsx:331)
• common.select: placeholder of the column picker in feature flag targeting rules (FeatureFlagSettingsModal.tsx:509)
• titles.unsubscribe: Open Graph image title on the reports unsubscribe page (reports-unsubscribe.$token.tsx:20). The text matches the page title already set there.
• apiNotifications.errorOccured in Organisations.tsx:314: the key does not exist, but common.errorOccured has the same text and placeholder, so the call now uses that instead of adding a duplicate.

Only en.json is edited. The other locales come from Crowdin and will pick the new keys up on the next sync.

Separate from this PR: in the Crowdin output, project.metrics.filterKV in de.json drops {{metricKey}} and in uk.json swaps {{metricKey}} and {{customEventName}}. I left those for Crowdin rather than editing the generated files.

Testing

Checked on main that none of the four keys exist in any locale file. In web: npm run lint, npm run format:check, npm run typecheck and npm run knip all pass.

AI assistance

Prepared with AI assistance and reviewed line by line. Claude Opus 5.5 in Claude Code found the missing keys and drafted the change.

Checklist

• Database: no migrations needed.
• Edition coverage: the strings live in the web app both editions use; no edition-specific code changed.
• Documentation: no changes needed, these are UI strings only.
