fix(web): allow auto balance clicks after manual selections

[maria-rcks]

the proposed change was reverted in 04eb562641ad3eab4accbdce55b9d7ca5da3660c. this pr now has zero changed files and should not be merged.

a direct blacksmith check with the locked base ui 1.5.0 primitives covered 24 cases. switching manual → auto already calls recovery once on the baseline; the proposal called it twice for pointer, enter, and space in both controls. the original reported failure has not been reproduced on current main.

Refs #12688. this pr does not fix or close that issue.

🟡 Medium components/BranchToolbar.tsx:239

Clicking Auto balance invokes onAutoEnvironment twice, causing duplicate host-resource refreshes and draft-context writes. MenuRadioGroup.onValueChange already handles the "auto" value, so this onClick handler adds the second invocation; remove it so the selection uses a single event path.

apps/web/src/components/BranchToolbarEnvironmentSelector.tsx:150

Clicking Auto balance after a manual environment selection invokes onAutoEnvironment twice: the SelectItem click handler added here runs it, and selecting the item changes the controlled Select value to "auto", so the root onValueChange at lines 97-99 runs it again. The shared callback refreshes every host resource and writes draft context, causing duplicate refresh/state work per one user selection. Keep the recovery call in only one selection path (or prevent the duplicate event).

Approvability

Verdict: Would Approve

Macroscope's review found this PR approvable — The final head has no effective changes relative to base: the temporary Auto balance callback modification was reverted, leaving the existing toolbar behavior intact. The cited duplicate-callback concern applies to that reverted intermediate state, not to the reviewed diff.
