Restore the default when theme is removed.

When the reactive theme changes from 'dark' to undefined, this condition does not update the mounted panel's theme signal. The panel therefore remains dark. Call setTheme with the documented default and assert the transition in a test.

🐛 Suggested fix 
-          theme && devtools.setTheme(theme)
+          devtools.setTheme(theme ?? 'system')
📝 Committable suggestion

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

Suggested change
theme && devtools.setTheme(theme)
devtools.setTheme(theme ?? 'system')

This follows the same pattern as withDevtools (theme && devtools.setTheme(theme)), which was suggested in #10609. I'd rather keep the panel consistent with it. If resetting to the default is wanted, it should be changed in both places, so I think that's better as a separate PR.

@n-satoshi061, thanks for the clarification. I verified that withDevtools also uses theme && devtools.setTheme(theme) in packages/angular-query-experimental/src/devtools/with-devtools.ts at Line 146. The panel now follows that same behavior.

The reset case remains possible in both APIs, but I agree that changing only the panel is not appropriate for this PR. I will not press for that change here.

Learning: In `tanstack/angular-query-experimental`, `withDevtools` in `packages/angular-query-experimental/src/devtools/with-devtools.ts` updates an existing devtools theme only when `theme` is truthy. `injectDevtoolsPanel` in `packages/angular-query-experimental/src/devtools-panel/inject-devtools-panel.ts` follows the same pattern. Removing a reactive theme does not reset the mounted devtools theme in either API; a reset change should consider both APIs together.
