feat: add PostgreSQL community analytics

[KingDoxik]

Summary

• replace the self-hosted ClickHouse analytics runtime with a synchronous PostgreSQL event store
• preserve the capture endpoint contract for a minimal allowlist of lifecycle events and trusted revenue events
• add a versioned, storage-neutral analytics event schema and migration suitable for future exports
• keep built-in revenue analytics while removing custom analytics processing, VoidQL handlers, queues, workflows, and ClickHouse infrastructure
• remove advanced analytics routes from the Community web app while retaining the built-in revenue, subscriber, trial, and churn views
• update self-host configuration, documentation, smoke coverage, and authorization manifests

Why

Community deployments should retain useful revenue analytics without operating a separate analytics database or asynchronous processing pipeline. A portable event record keeps the stored data explicit and migration-friendly.

Impact

• self-hosted deployments no longer require ClickHouse
• unsupported and custom SDK events are reported as rejected and are not persisted
• supported lifecycle events and server-trusted revenue events are written synchronously to PostgreSQL
• existing analytics metadata tables are retained to keep upgrades non-destructive, but advanced analytics operations and UI routes are no longer mounted

Validation

• Repository CI: publication and platform boundaries, purchase/restore contracts, build, lint, typecheck, and unit tests
• Self-host Compose: image startup, integration tier, end-to-end tier, and release end-to-end tier
• security audit, secret scanning, OSV scan, and PR package publication
