feat(analytics): build-time bake + telemetry depth (#336)

Bake PostHog + Sentry into the published Docker image (SNAPOTTER_ANALYTICS
build arg, codegen script). Delete entire consent system. Move event emission
to BullMQ worker. Add cross-tier identity stitching, Sentry performance
tracing on both tiers, frontend funnel events. Fix stateful regex bug.
