Add global overrides to list and local options

[chrishoage]

Summary

Expose rclone’s global _config and _filter overrides on /operations/list and /options/local.

For /operations/list, _filter changes which entries are returned. _config is included for completeness alongside the other global override.

For /options/local, both _config and _filter affect the effective options returned in the response.

Changes

• Add _config and _filter parameters to /operations/list
• Add _config and _filter parameters to /options/local
• Include the overrides in the generated request schemas
• Regenerate openapi.json and types.d.ts
