feat(config): add auto_expand_history field

[IamCoder18]

Summary

Add auto_expand_history boolean configuration field to mirror the CLI config schema change from the kilocode repo. This field controls whether command history is automatically expanded when searching.

Required for Kilo-Org/kilocode#8759

Verification

• Added the field to apps/web/src/app/config.json/extras.ts in the top bucket with appropriate description and boolean type
• Added test assertion in apps/web/src/tests/cli-config-schema.test.ts to verify the field is included in the merged schema
• All existing tests pass, confirming the schema merge works correctly

Visual Changes

Reviewer Notes

• This change maintains synchronization between the kilocode CLI schema and the cloud config overlay
• The field follows the same pattern as other top-level boolean configs like remote_control and codebase_search
• Tests verify the field appears in the merged schema at https://app.kilo.ai/config.json
