[codex] Move project grouping to General settings

[juliusmarminge]

Why

Project grouping is currently exposed as a sidebar-specific organization control even though the preference affects project identity across the application. Keeping it beside sorting controls makes its scope unclear.

Root cause

The grouping preference was surfaced from the legacy sidebar menu instead of the global settings surface.

Fix

• add Project Grouping to Settings → General
• preserve the previous repository-path grouping choice when toggling
• remove the duplicate control from the legacy sidebar menu

This PR contains only the web setting relocation and does not change Sidebar V2 grouping behavior.

Verification

• targeted formatting and lint
• vp run --filter @t3tools/web typecheck
• vp test run apps/web/src/components/settings/SettingsPanels.logic.test.ts — 7 tests passed

Note

Move project grouping control from sidebar sort menu to General settings

• Removes the 'Group projects' radio group from ProjectSortMenu in Sidebar.tsx; the sidebar sort menu now only controls sort order and thread preview count.
• Adds a 'Project Grouping' toggle to GeneralSettingsPanel in SettingsPanels.tsx that maps to sidebarProjectGroupingMode.
• Persists the last non-separate grouping mode to localStorage via new helpers in SettingsPanels.logic.ts so toggling back restores the previous mode.
• Restoring defaults in General settings now also resets sidebarProjectGroupingMode.

Note

Low Risk
UI relocation only; same setting key and grouping behavior, with tests for toggle mapping and no auth or data-path changes.

Overview
Project grouping is edited in Settings → General instead of the legacy sidebar project sort menu, so it reads as an app-wide preference rather than a sidebar-only sort option.

The new Project Grouping switch still drives sidebarProjectGroupingMode: off sets separate; on restores the last enabled mode (repository or repository_path). That last mode is kept in a ref and in localStorage when you turn grouping off, so toggling back does not collapse repository_path into repository. Restore-defaults and the changed-settings list now include project grouping.

The Group projects radio block and related props/handlers are removed from ProjectSortMenu in Sidebar.tsx; sort/preview controls in that menu are unchanged.

Approvability

Verdict: Approved

UI reorganization moving project grouping controls from sidebar menu to General settings. The underlying functionality is unchanged; only the control location and a minor localStorage enhancement for remembering the last enabled mode are added. Self-contained with unit tests.
