Clarify observability: surface Data API (edge logs) before PostgREST in overview

Clarify observability: surface Data API (edge logs) before PostgREST in overview targets a $40.0B = global observability + API management market (~20,000 enterprises x $2,000/year avg developer-tooling + $1.99B platform spend aggregated) total addressable market with medium saturation and a year-over-year growth rate of 18%+ combined CAGR for observability and API management over next 3–5 years.

Key trends driving demand: API-first backends -- teams are building more HTTP/edge APIs, increasing demand for edge/API observability.; Edge & serverless -- migrations to edge runtimes surface new latency/failure modes needing dedicated metrics.; Consolidation of observability -- vendors and platforms are bundling logs, metrics, and traces for correlated troubleshooting.; Developer experience commoditization -- platforms compete on DX by exposing precise, integrated telemetry for rapid debugging..
