Update telemetry configuration

Per-category telemetry capture settings for browser events.

Forwarding of captured telemetry to an external destination. Independent of what is captured: export is off unless explicitly enabled here, even when an export destination is configured. In a PUT (full replace) an omitted export block resets export to off, the same as omitted categories turn off; in a PATCH an omitted field leaves the current setting unchanged.

Telemetry configuration for a browser. Selection is opt-in. Omit the browser key (or send an empty object) to capture the default set: lightweight operational signals (control, connection, system, captcha). Within browser, only the categories you set enabled: true are captured; anything omitted is off. The CDP categories (console, network, page, interaction) and screenshot are off by default and must be opted into. A browser config with nothing enabled clears the telemetry configuration. The monitor category (CDP collector health) is not configurable here; it flows automatically whenever a CDP category is captured.
