Vance Ingalls fb24ecac22 fix(studio): make setRightPanelTab itself flat-aware, not just the direct tab click
Review feedback on #2497 (Rames D Jusso) found a real gap: the exclusivity
this PR introduced only applied to the direct in-panel tab click, which
calls setExclusiveRightInspectorPane. Every OTHER caller that reaches
setRightPanelTab("design"|"layers") — element select (useDomSelection.ts),
closing block-params (App.tsx), the header Inspector button
(StudioHeader.tsx), and even this PR's own "!inspectorTabActive" entry
branch in handleInspectorPaneButtonClick — went through
trackedSetRightPanelTab's old unconditional additive
`{...panes, [tab]: true}`, reproducing the exact "both tabs highlight, only
one renders" bug this PR claims to fix. Confirmed via the reviewer's traced
repro: fresh boot, click Layers tab while no inspector tab is yet active →
rightInspectorPanes ends up {design:true, layers:true}.

Fixed at the reviewer's preferred choke point: trackedSetRightPanelTab
itself is now flat-aware, applying the same exclusive-radio update
setExclusiveRightInspectorPane does whenever STUDIO_FLAT_INSPECTOR_ENABLED
is on, falling back to the legacy additive update otherwise. This closes
the gap for every current and future caller of setRightPanelTab, not just
the one call site this PR touched.

New usePanelLayout.test.ts cases pin both directions: setRightPanelTab
stays additive under flat=off (legacy split-view behavior unchanged), and
enforces exclusivity under flat=on even when called directly (not through
the tab-click handler) — using the vi.doMock(manualEditingAvailability)
pattern already established in PropertyPanel.test.tsx for flag-dependent
module state.

Full studio suite (2643 tests) green; typecheck/oxlint/oxfmt clean.
