Description

Adds bidirectional highlighting/selection sync between the map and data table, persistent multi-feature selection, and a collapsible/resizable table panel. Second in the data table improvement series, building on PR1's toolbar and context menu.

Selection (DataTable)

• New checkbox column; header checkbox selects/deselects all currently visible rows in one action
• Ctrl/Cmd-click a row to toggle its selection; Shift-click selects a range from the last-clicked row (falls back to a single-row toggle if there's no prior anchor yet)
• Selection is tracked in a new selection reducer, scoped per layer, and resets on layer switch

Map ↔ table sync

• Hovering a map feature highlights and scrolls to its table row; hovering a table row highlights the feature on the map — consistent styling in both directions (previously cursor-hover fell through to @dhis2/ui's native grey tr:hover style while map-hover showed our own blue highlight)
• Left/right-clicking a map feature scrolls the table to its row without changing selection; Ctrl/Cmd-click also toggles selection
• Double-clicking a table row zooms the map to that feature
• A row that's both selected and hovered now shows the hover color, not the selected color

Filtering

• "Show only selected features" and "show only in view" toolbar toggles filter both the table and the map
• "Show only in view" now uses true bounding-box overlap instead of centroid-only, and correctly handles map viewports that cross the antimeridian

Zoom actions

• "Zoom to layer" added to the table's row context menu (previously map-only)
• "Zoom to selected features" added to both the map and table context menus, disabled when nothing's selected; zooms to the combined bounds of every selected feature

Table panel (BottomPanel)

• Collapse/restore button and double-click-the-header-to-toggle, shrinking the panel down to just the toolbar strip
• The resize handle is always available, including collapsed: dragging up exits collapsed mode and resizes live; dragging down to the floor enters collapsed mode
• Restoring (button, double-click, or dragging back up) returns to the exact height the panel had before collapsing

Bug fixes

• Long unbroken text (e.g. URLs) in table cells now wraps instead of overflowing
• O(n·m) .includes() scans in selection filtering replaced with O(1) Set lookups
• Fixed a stale-effect bug where Ctrl-clicking a table row (or any selection change) re-triggered the map-click scroll effect and yanked the table back to a previously map-clicked row
• Fixed a crash in the map context menu's mapStateToProps when no context menu is open
• Fixed the toolbar layout bug where the resize handle's runaway flex-basis squeezed the layer name to zero width

maps-gl

• New Cluster.setVisibleIds() override: "show only selected" now re-clusters from the filtered feature set (via source.setData()) instead of applying a GL filter expression, which can't target cluster circles (they carry no per-feature id). Applies to client- and donut-clustered event layers; server-clustered layers are unaffected since their data table is already unsupported today (unrelated pre-existing limitation)
• Layer#panToFeature() now accepts an array of ids, fitting the map to their combined bounds

In general this looks good. I did leave some comments which you can take or leave.

Another thing I noticed while reviewing was a general pattern where I saw:

• A diff in the prop-types
• A diff in the props in the function signature
• No changes in the function body
• A diff in the JSX where the added props being passed down to descendants

So this is prop-drilling and you could consider addressing it by introducing a/multiple context providers and maybe some hooks. But this is just a casual comment. I didn't look into it deeply and also realise this is a codebase with a mix of function and class components, so it could get messy.

The merge-base changed after approval.

Thanks for your review @HendrikThePendric, I addressed your specific comments and marked them as resolved. On the prop-drilling observation, agreed, but don't want to extend this PR's scope now. I will explore using a context as a PR stack clean-up or at a later stage.
