docs(base): fix dashboard date filter value format

[chenfan414-hash]

Summary

• correct the dashboard date-filter value shape for datetime, created_at, and updated_at
• document ExactDate and relative-date array forms
• clarify that empty checks omit value

Evidence

The current example uses a bare epoch millisecond value, which produces a field-type mismatch. Other Base skill references consistently document date filters as ["ExactDate", "<epoch_ms>"].

Closes #2315

Testing

Documentation-only change; cross-checked against lark-base-data-query.md and lark-base-data-query-guide.md.

Summary by CodeRabbit

• Documentation
  • Updated filter guidance for date and timestamp fields.
  • Added support details for exact dates and relative date keywords.
  • Clarified operator restrictions and when value fields should be omitted.

📝 Walkthrough

Walkthrough

The dashboard date filter documentation now describes date-keyword arrays, exact-date timestamp values, valid operators, and omitted values for empty-value operators.

Changes

Dashboard date filter documentation

Layer / File(s)	Summary
Date filter value contract skills/lark-base/references/dashboard-block-data-config.md	Date filter values now use string arrays with date keywords or exact-date timestamp strings. The documentation restricts supported operators and omits value for isEmpty and isNotEmpty.

Estimated code review effort: 1 (Trivial) | ~5 minutes

Mergeability Score: 🟡 Moderate · up to 6a99b

The documentation still lists unsupported datetime operators, which could lead users to send invalid date filters. Update the remaining table before merging.

Make the datetime operator tables consistent.

This row correctly removes isGreaterEqual and isLessEqual for date fields. However, Line 32 still lists both operators for datetime. The neighboring contracts in skills/lark-base/references/lark-base-data-query.md Lines 297-305 and skills/lark-base/references/lark-base-data-query-guide.md Lines 44-48 also list only five supported date operators. Remove the two inclusive operators from Line 32 to prevent users from sending invalid date filters.

Proposed fix

-datetime: is, isGreater, isGreaterEqual, isLess, isLessEqual, isEmpty, isNotEmpty
+datetime: is, isGreater, isLess, isEmpty, isNotEmpty
