fix: preserve datetime timezone on row updates

[cursor]

Summary

• Fixes #2870: updating a row from the Console re-submits datetime columns as timezone-less local ISO strings, so the API stores them as UTC and values drift by the browser offset on every save.
• Canonicalize datetime scalars and arrays to UTC in buildPayload, matching the existing filters path (new Date(value).toISOString()).
• Adds unit coverage for round-trip / array / null / bigint behavior.

Test plan

• bun run test:unit -- .../rows/store.test.ts (5 passed)
• Manually: create a row with a datetime in a non-UTC timezone, update a different field without touching the datetime, confirm the datetime instant is unchanged

Greptile Summary

This PR prevents datetime values from drifting during row updates by converting local datetime input strings back to UTC ISO strings before submission.

• Adds datetime normalization for scalar and array fields in buildPayload.
• Preserves null, empty, invalid, and non-string values.
• Adds focused tests for timezone round trips, arrays, nullable values, and existing bigint conversion.

Confidence Score: 5/5

The PR appears safe to merge, with no concrete regressions identified in the reachable row creation or update paths.

Current datetime editors provide local datetime strings that the new conversion correctly restores to UTC, while timezone-bearing generated values remain unchanged and existing null, invalid, and bigint behavior is preserved.
