Subject: [PATCH] fix(lint): enable no-floating-promises rule and handle all
 promises
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Enable @typescript-eslint/no-floating-promises to catch unhandled
promise rejections. Fixes:
- HealthGateway.sendInitialData: void for fire-and-forget
- DomainHealthService.checkDomainHealth: void for startup check
- main.ts bootstrap: .catch() with proper error handling
- MetricsPersistenceService.flushBatch: void for async batching
