feat(cli): add docs.yml setting to disable environment editing

[kafkas]

Description

Linear ticket: Refs FER-9706

Adds a new settings.disable-environment-editing option to docs.yml. When enabled, API reference pages can display the configured base URL without allowing users to double-click and edit it, while preserving the current editable behavior by default for backward compatibility.

Changes Made

• Added disable-environment-editing to the docs.yml schema and regenerated the docs config artifacts
• Parsed the new setting into the CLI's docs configuration output
• Added an unreleased changelog entry for the new docs.yml feature

Testing

• Unit tests added/updated
• Manual testing completed

main (generator): generator-only time via --skip-scripts (includes Docker image build, container startup, IR parsing, and code generation — this is the same Docker-based flow customers use via fern generate). main (E2E): full customer-observable time including build/test scripts (nightly baseline, informational). Delta is computed against generator-only baseline.
⚠️ = generation exited with a non-zero exit code (timing may not reflect a successful run).
Baseline from nightly runs on main (latest: 2026-04-17T04:58:39Z). Trigger benchmark-baseline to refresh.
