Alaister YoungandAlaister Young 240bfce7f6 [FE-4198] feat(studio): select a range of logs with shift-click (#50381)
Shift-clicking a log row checkbox now selects every row between the last
clicked row and the clicked one, so you can grab a consecutive block of
logs to copy without checking each one. Applies everywhere the shared
`LogTable` renders: Postgres/API/Auth/Edge Functions logs and the Logs
Explorer.

**Added:**
- `getShiftClickSelection` in `Logs.utils.ts`: pure helper that computes
the next selection from the ordered row keys, the current selection, the
anchor row, and the clicked row. Adds the inclusive range in either
direction. If the whole range is already selected it deselects the range
instead. Falls back to a plain toggle when there's no usable anchor.
Covered by unit tests, plus `LogTable` component tests for range select,
the no-anchor fallback, anchor clearing, and range deselect.

**Changed:**
- `LogTable` tracks the last toggled row as the range anchor (a ref,
since it's only read in handlers). The anchor is set by plain clicks,
shift-clicks, and the Shift+Space row toggle, and cleared whenever the
selection becomes empty (toggling off the last row, plain row click,
Escape, action bar clear, select-all then deselect-all, or a new query
loading).
- The checkbox cell handles `onClick` instead of `onCheckedChange` so
the shift key is available. Keyboard Space on a focused checkbox still
toggles it, since Radix dispatches a click for it.
- A shift mousedown on the checkbox cell is prevented so the browser
doesn't start a text selection across rows.

Unified Logs has its own row selection (TanStack Table) and is not
changed here.

## To test

- Open any log page with a decent number of rows, e.g. Postgres logs.
Click one checkbox, then shift-click a checkbox several rows below.
Every row in between should be checked and the action bar should show
the count. Repeat upward.
- Shift-click a range that's already fully selected: the range should
clear, and rows outside it stay as they were.
- Plain-click a row's message text (not the checkbox): side panel opens
and the selection clears. A following shift-click should just toggle
that one row.
- Press Escape or the action bar's clear button, then shift-click: also
just a single toggle.
- Focus a row with the arrow keys, press Shift+Space, then shift-click a
lower checkbox: the range should extend from the keyboard-toggled row.
- Tab to a checkbox and press Space: it should still toggle.
- After a shift-click, confirm no text is highlighted across the rows.
- Copy as JSON/Markdown/CSV still copies the selected rows in display
order.

## Summary by CodeRabbit

- **New Features**
- Added shift-click range selection to the logs table for selecting or
deselecting consecutive rows.
  - Preserved single-row selection when range selection is unavailable.
- Improved selection behavior when clearing selections or changing log
queries, preventing stale range anchors.

- **Tests**
- Added coverage for forward and reverse range selection, deselection,
partial selections, fallback behavior, and input immutability.
