fix(web): keep right panel controls clickable

[maria-rcks]

The Electron drag region around scrollable right-panel tabs intercepted the header controls, and maximizing the panel hid its restore control with the collapsed chat column. This moves the open-panel controls into the tab bar's no-drag area while keeping the closed-state controls in the chat header, so maximize, restore, terminal, and panel toggles remain reachable. Web typecheck, targeted lint, formatting, and real-app interaction checks pass; the existing component tests are blocked before collection by the repository's current vite-plus/test config error.

Note

Low Risk
UI layout and pointer-event behavior only in the chat workspace header and right panel tab bar; no auth, data, or API changes.

Overview
Moves maximize/restore and panel toggle controls into the inline right panel tab bar when that panel is open, instead of leaving them in the fixed chat header where Electron’s tab-bar drag region could swallow clicks.

rightPanelControlsInPanel now requires the panel to be present and open, so the header shows panelLayoutControls only while the inline panel is closed; open inline panels receive layoutControls on RightPanelTabs inside a [-webkit-app-region:no-drag] cluster. RightPanelTabs tightens title-bar padding when those controls are embedded so window chrome spacing stays correct.

Note

Fix right panel controls rendering in 'ChatViewContent' and 'RightPanelTabs'

• ChatViewContent passes an inline control cluster (maximize and toggle controls) to RightPanelTabs only while the right panel is open
• The workspace header renders its panel layout controls only when the panel is closed or not present
• Risk: RightPanelTabs changes tab-bar padding for inline desktop mode when layout controls are present, replacing the native-controls inset plus six rem with just the native-controls inset

Approvability

Verdict: Approved at b3ceeab

Macroscope's review found this PR approvable — This is a contained UI bug fix that moves existing right-panel controls into an Electron no-drag region when the panel is open and preserves closed-state header controls. Its runtime impact is limited to control reachability and title-bar spacing, with no data, API, security, or product-default changes.
