Option to Disable Structured Logging Either Project Wide or Org Wide within UI

### Problem Statement

Currently it is only possible to disable Structured Logging via the SDK config, see related article here: https://sentry.zendesk.com/hc/en-us/articles/40482848456731-How-do-I-disable-Structured-Logging

Specific related user ask:

They have old iOS app versions are still sending logs in production that they want to prevent log spikes to manage spend costs. While are actively updating the current SDK Logging config (to disabled) the older versions can continue to send logs.

They want to have the ability to maintain their current PAYG budget but are unable to set a limit on Logs to avoid spend cost.

### Solution Brainstorm

Allow for a Project Setting, Org Settings or DSN config that allows for the full enable/disablement of Logging with the UI that does not require SDK side config.

### Product Area

Settings - Developer Settings

The issue identifies Settings - Developer Settings as the product area but names no files, tests, or entry points. Start by tracing the existing Structured Logging SDK configuration and the project and organization settings surfaces. Done should include a UI-controlled way to disable logging for the requested scope and coverage for older SDK versions.
