Fix duplicate untranslated string in DatabaseRefreshDialog

[kanweiwei]

web/src/components/DatabaseRefreshDialog.tsx has two issues:

1. Line 61-62: Line 61 uses t('app.databaseConnectionLost') for the heading, but line 62 repeats the same text as a hardcoded English paragraph right below it. The paragraph should either use a different i18n key with helpful guidance or be removed as redundant.

2. Line 94: "(Refresh Page)" is hardcoded instead of being part of the i18n key.

What to do:

1. Read web/src/components/DatabaseRefreshDialog.tsx
2. Replace the hardcoded paragraph with an i18n key (e.g. app.databaseConnectionLostDescription)
3. Include "(Refresh Page)" in the button's i18n key or create a separate key
4. Add the new keys to all 4 locale files in packages/i18n/src/locales/
5. Run: pnpm -C web run typecheck

Skills needed: TypeScript, basic i18n

Estimated time: 15 minutes

The duplicate English paragraph on line 62 and the hardcoded "(Refresh Page)" need proper i18n keys. I'd handle this by adding app.databaseConnectionLostDescription and updating the button text key, then updating all four locale files. I can have a PR up in under an hour—I work with TypeScript/Next.js i18n regularly.

The duplicate English paragraph on line 62 and hardcoded "(Refresh Page)" on line 94 need proper i18n keys. I'd handle this by adding app.databaseConnectionLostDescription and updating the button text key, then populating all four locale files. I can have a PR up within an hour.
