Companion to TabularisDB/tabularis#1474 (host issue TabularisDB/tabularis#1473).

The host's ForeignKey gains an optional ref_schema. Without it, a foreign key into another schema (billing.carry_forwards → core.organizations) makes the Related Records panel query billing.organizations and fail. Both FK queries already select foreign_schema_name; row_to_foreign_key now emits it as ref_schema, so get_foreign_keys, get_all_foreign_keys_batch and get_schema_snapshot all carry it. The shape matches the built-in driver, and older hosts ignore the extra field.

Validation:

• New live_db test with a cross-schema FK asserts ref_schema from both RPCs. It fails without the change (left: Null) and passes with it.
• 449 library and 5 binary tests pass; cargo clippy --all-targets -- -D warnings and cargo fmt --all -- --check pass.
• Host parity suite pointed at this build: parity_get_foreign_keys, parity_get_foreign_keys_composite_table and parity_get_foreign_keys_cross_schema pass with the host change; they fail against rc.14. No new parity failures.
• Manual: installed into a Tauri dev build against a real multi-schema database; the Related Records panel resolves core.organizations.

Code Review Summary

Status: No Issues Found | Recommendation: Merge

row_to_foreign_key now emits ref_schema from foreign_schema_name, which both FK queries already select (::text). Because get_foreign_keys, get_all_foreign_keys_batch and get_schema_snapshot all go through this function, they all carry the field. The field is omitted when the value is NULL, so older hosts are unaffected. The new live_db test covers both RPCs. I did not run the tests.
