Accept daemon settings in the published editor schema (#6621)

* fix(config): accept daemon settings in the published editor schema

The website schema omitted accepted configuration fields, so editors
rejected valid browser, profile, plugin and metadata settings. Regenerate
from the daemon schema and guard the published artifact against drift.

* fix(config): preserve proxy help when regenerating the schema

Keep the existing editor descriptions in the source schema so regeneration retains them. The new regression fails when the proxy descriptions disappear.

* test(usage): create SQLite store fixtures in one transaction

The Windows plugin suite exceeded its five-second test deadline while creating and exercising the first OMP store fixture. Commit the fixture as a unit rather than flushing each inserted row separately; preserve the read-only discovery assertions.

* test(config): show structured schema validation errors
