docs: enterprise component field notes (ag-grid, map, react flow)

[amsraman]

Sixth batch of upstreaming Reflex Build's AI-builder knowledge base. Enterprise component gaps:

AG Grid

• Two new pages for previously-undocumented features: Tree Data (tree_data/get_data_path FunctionVar pattern, conditional paths, aggregation) and Master-Detail (detail_cell_renderer_params with successCallback) — both registered in the sidebar
• index.md: selection-changed handler signature (list[dict], and the exact mismatch error a dict signature raises), floating filters, enterprise multi-column filter
• cell-selection.md: fill-handle modes/direction, per-column suppression, nonexistent-prop pitfalls
• model-wrapper.md: bug fix — docs said class_model=, the actual kwarg is model_class= (verified against reflex_enterprise); fixed-height requirement, _is_authorized example
• value-transformers.md: formatter patterns and cell renderers (incl. the @rx.memo-via-lambda requirement for interactive renderers)

Map: Leaflet icon-options dicts (no rxe.map.icon exists), map-API pitfalls (function not class, don't store in state, positional args), zoom debounce.

React Flow: controlled vs uncontrolled flows, the where-changes-get-applied rule (apply_node_changes in component wiring, never state code), provider takes no handlers, screen_to_flow_position usage.

Memories already covered by existing pages (pivot mode, basic usage, value getters, editing) were skipped; one memory's unverifiable event-payload claim was rejected. Pre-commit incl. pyright clean.

Avoid putting detail callbacks in state

When this dynamic variant is copied with STATIC_DETAIL_PARAMS above, the state var contains the get_detail_row_data lambda. Reflex state vars are serialized for the client; arbitrary callables inside a dict are not preserved, so the detail grid loses the callback and expanded rows cannot load. Keep renderer params with JS callbacks as module-level props or rebuild them in the component instead of storing them in rx.State.

Greptile Summary

This documentation PR (sixth batch of AI-builder knowledge-base upstreaming) adds two new AG Grid enterprise pages (Tree Data, Master Detail), fixes a class_model= → model_class= kwarg typo, and enriches several existing pages with previously-undocumented patterns for Map, React Flow, cell selection, formatters, and selection-changed handlers.

• New pages: tree-data.md covers data_path_key / get_data_path FunctionVar patterns and dynamic rx.cond path switching; master-detail.md documents detail_cell_renderer_params with the correct module-level (not state-var) placement for callable params, explicitly addressing the previously-flagged serialization issue.
• Existing page fixes: corrects model_wrapper kwarg from class_model= to model_class=, adds _is_authorized / column customization examples, floating filters, on_selection_changed handler signature, fill-handle config, Map API positional-arg requirement, and React Flow controlled vs. uncontrolled flow rules.

Confidence Score: 5/5

Documentation-only changes; no runtime code is modified. Safe to merge.

All changes are Markdown documentation and sidebar/title registration. The patterns shown are technically sound and stated to be verified against reflex_enterprise. The only issue found is a minor method-name inconsistency in model-wrapper.md between a pre-existing bullet list and the new code example added in this PR.

docs/enterprise/ag_grid/model-wrapper.md — the overridable-methods bullet list uses _get_columns_defs (plural) while the new code example calls _get_column_defs (singular).

Important Files Changed

Filename	Overview
docs/enterprise/ag_grid/model-wrapper.md	Fixes class_model= → model_class= kwarg bug, adds fixed-height requirement and _is_authorized example; pre-existing bullet list names _get_columns_defs (plural) while new code example calls _get_column_defs (singular), creating an inconsistency on the same page.
docs/enterprise/ag_grid/master-detail.md	New page documenting master-detail grids; correctly uses module-level objects for callback-bearing params and explicitly warns against storing lambdas in state vars.
docs/enterprise/ag_grid/tree-data.md	New page for tree data with data_path_key and get_data_path FunctionVar patterns; dynamic path switching via rx.cond and group_default_expanded docs look correct.
docs/enterprise/ag_grid/index.md	Adds floating filter, enterprise multi-column filter, and on_selection_changed handler documentation with correct list[dict] signature; all additions are accurate.
docs/enterprise/ag_grid/value-transformers.md	Adds formatter pattern comparison (inline JS, Python lambda, FunctionStringVar) and cell_renderer section with @rx.memo requirement for interactive renderers; patterns are well-documented.
docs/enterprise/map/index.md	Adds custom marker icon dict pattern, map API usage pitfalls, positional-args requirement, and zoom debounce guidance; all accurate.
docs/enterprise/react_flow/interactivity.md	Adds on_connect handler, controlled vs uncontrolled flow explanation, and the where-changes-get-applied rule for apply_node_changes; all technically accurate.
docs/enterprise/react_flow/components.md	Adds note that FlowProvider does not accept event handlers and shows correct handler placement on rxe.flow; example is correct.
docs/enterprise/react_flow/hooks.md	Adds FlowProvider dependency note and screen_to_flow_position usage example for on_connect_end; documentation is accurate.
docs/enterprise/ag_grid/cell-selection.md	Adds fill-handle direction/mode options, non-existent-prop pitfall note, and per-column suppress_fill_handle; documentation is accurate.
docs/app/reflex_docs/pages/docs/init.py	Adds tree-data.md and master-detail.md to the manual_titles mapping; straightforward and correct.
docs/app/reflex_docs/templates/docpage/sidebar/sidebar_items/enterprise.py	Registers Tree Data and Master Detail sidebar items under the AG Grid section between Pivot Mode and Theme; ordering and paths look correct.
