feat(studio): object field designer Tier-2 ergonomics

[xuyushun441-sys]

Summary

Tier-2 editing ergonomics for the object field designer — the "human makes simple modifications to AI-authored objects" path.

• Default value — a type-aware editor in the field inspector: tri-state select for boolean (— / True / False), number input for numeric, an option dropdown for single picklists, text otherwise. Omitted for computed / relational / media / structural types (no literal default). Persists on Field.defaultValue.
• Duplicate field — clones the selected field directly below itself with a collision-free name (<name>_copy, _copy_2, …) and a "(copy)" label, then selects the clone.
• Keyboard reorder — Alt+↑/↓ on a focused field row swaps it with its nearest same-group neighbour (never crosses groups), reusing the existing reorder write path. A11y win for non-drag users.

All new strings localized (en-US / zh-CN).

Tests

+11 RTL cases: default-value commit per kind, computed/lookup omit the editor, boolean uses a select; duplicate naming + selection + collision handling; Alt-arrow reorder + bounds + plain-arrow-noop + read-only inert. metadata-admin suite green (97); tsc clean; 0 lint errors.

Not included (still open from the evaluation)

• Bulk multi-select of fields; conditional visibility; a full validation-rule editor — larger surfaces, deferred.
• Help text was intentionally skipped: the field model has no distinct inline-help property (only description + placeholder).

Note

Live browser verification remains blocked by a local framework dev-backend auth issue (/api/v1/auth/get-session 404 → console SPA can't restore a session), unrelated to this change; covered by unit tests.
