Replace the Freemarker SQL Lab with a React single-page app (React 18,
Ant Design 5, TanStack Query) under exec/java-exec/src/main/resources/
webapp, backed by new REST resources. Developer documentation is under
docs/dev, with a per-page UI reference in docs/dev/ui.

SQL Lab: multi-tab Monaco editor with server-side tab persistence,
schema explorer with schema sampling for dynamic-schema tables,
server-side pagination of large results, a backend result cache, query
profiles, saved queries, and saving a query as a view or materialized
view. Includes a SQL dialect transpiler (sqlglot on GraalPy).

Visualizations and dashboards: chart, metric and choropleth map
visualizations (US states, counties and ZIP codes with lazy-loaded
GeoJSON), dashboards with images and AI Q&A, and a geospatial filter
builder that turns drawn shapes into ST_ predicates.

Projects: datasets, saved queries, visualizations, dashboards and a wiki
grouped by project, with sharing, a per-project schema cache, and PDF
export of wiki pages.

Prospector AI assistant: chat over OpenAI, Anthropic, Ollama and
enterprise providers (proxy, TLS, custom headers), with project context,
schema and function metadata, credential redaction, a sendDataToAi
control, generated reports saved to the project wiki, and an AI
analytics dashboard built on a JSONL event log queried with Drill SQL.

Workflows: replace the query scheduler with workflows, a saved query on
a schedule followed by a pipeline of conditional actions (record alert,
save to table, email). Includes a condition language and builder,
templates, dry runs, cluster-safe scheduling, crash recovery, run-as-
owner permissions, a run log queried with Drill SQL, migration of
existing schedules, and a user and admin guide.

Admin: data source and credential management, storage plugin logos,
cluster, metrics, options, logs and threads pages.
