fix(public-api): pass warehouse_client so dashboard filters apply acr…

[NaveenCode]

Summary

• Fixes public dashboards where a filter only applied to charts from the exact same source table, ignoring other charts sharing the same column from a different table.
• get_public_chart_data() called resolve_dashboard_filters_for_chart() without a warehouse_client, causing it to fall back to a strict schema/table match instead of the correct column_exists() check.
• Passed warehouse_client in, matching private mode and every other public endpoint (table preview, map, CSV export).

Affected

pie, line, bar,number and pivot_table charts on public dashboards.

Fixes DALGO-1678

Summary by CodeRabbit

• New Features
  • Public report table previews and total-row results now support optional dashboard filters.
  • Dashboard filters are resolved against the report’s configured filter definitions before chart data is generated.
  • Public dashboard charts now apply applicable filters more accurately.

Walkthrough

Public dashboard chart filter resolution now uses warehouse context. Public report table preview and total-row endpoints accept optional dashboard filters, resolve them against frozen report definitions, and include the resolved filters in chart payloads.

Changes

Public filter propagation

Layer / File(s)	Summary
Warehouse-aware filter resolution ddpui/api/public_api.py	Dashboard chart filter resolution obtains a warehouse client and passes it to resolve_dashboard_filters_for_chart.
Report table filter propagation ddpui/api/public_api.py	Report table preview and total-row endpoints accept optional dashboard_filters parameters. They parse and resolve valid JSON filters against frozen report definitions and pass the results into chart payloads. Invalid JSON produces no resolved filters.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🔵 Low · up to 55b87

Public dashboard requests containing truthy non-object filter values may return 404 instead of ignoring the invalid filter input. The risk is localized and the change is mergeable with explicit owner awareness and follow-up validation.
