Fix static dropdown options and remove terse mode

- Fix sri.getFieldOptions() call to pass drop-down node instead of parent field node
- Remove terse parameter from all services and serialization
- Increase safety limits by 10x: lists 10K items, strings 1MB, unknown types 10K chars
- Add form-list field metadata extraction in FTL macros
- Simplify McpFieldOptionsService to use CustomScreenTestImpl approach
- Clean up redundant _fixed.groovy file
