Batch-write analytics events instead of per-event inserts

[demilade18-git]

Description

Add an in-memory buffering layer that batches incoming AnalyticsEvent writes and flushes them every N seconds or M events, instead of issuing one INSERT per tracked event.

Changes

• Add TrackEventProvider with in-memory buffer
• Buffer flushes on both time (5s) and size (50 events) thresholds
• Buffer flushed on OnModuleDestroy for graceful shutdown
• Failed saves re-queue events back into the buffer
• Create analytics module infrastructure (module, entity, controller, providers)

Acceptance Criteria

• Buffer flushes on both time and size thresholds
• No events are lost on graceful shutdown (flush on OnModuleDestroy)
• Load test shows reduced DB write amplification vs. baseline

Closes #542
