* Add full import/export support for rules with versioned JSON schema
This commit implements comprehensive import/export functionality for rules,
allowing users to back up and restore their rule definitions.
Key features:
- Export rules to both CSV and NDJSON formats with versioned schema (v1)
- Import rules from CSV with full support for nested conditions and actions
- UUID to name mapping for categories and merchants for portability
- Support for compound conditions with sub-conditions
- Comprehensive test coverage for export and import functionality
- UI integration for rules import in the imports interface
Technical details:
- Extended Family::DataExporter to generate rules.csv and include rules in all.ndjson
- Created RuleImport model following the existing Import STI pattern
- Added migration for rule-specific columns in import_rows table
- Implemented serialization helpers to map UUIDs to human-readable names
- Added i18n support for the new import option
- Included versioning in NDJSON export to support future schema evolution
The implementation ensures rules can be safely exported from one family
and imported into another, even when category/merchant IDs differ,
by mapping between names and IDs during export/import.
