fix(web): keep PR controls readable in narrow panels

[Bil0000]

What changed

Keep pull request controls readable at the 360 px panel minimum. The tab row wraps its status and activity controls when needed. The Code toolbar stays on one row, with a shrinking commit selector and space reserved for the file count and controls. Total additions and deletions appear only in the PR header, with no duplicate toolbar totals at any width.

Why

Summary status and Timeline sorting were clipped. In Code, the file count overlapped the additions and deletions. This CSS-only fix applies to the shared PR page and chat panel; wider panels retain one row.

Verification

• Browser regression fails on the original layout and passes at 360, 420, 540, and 700 px, including resizing back down.
• Checked Summary, Timeline sorting, Code controls, long commit titles, and stacked/split diffs on both the PR page and chat side panel in an isolated app using a real PR.
• 118 focused PR detail and diff tests passed. Web typecheck, targeted lint, and formatting passed. Lint reports existing warnings outside the changed lines.
• Verified the toolbar has no duplicate totals at 360, 420, 540, and 700 px, while the PR header totals remain.
• Summary and Timeline can use an extra row at narrow widths. The Code toolbar stays 40 px high at 360, 420, 540, and 700 px.

📝 Walkthrough

Walkthrough

The code toolbar and tab bar now wrap on smaller widths. The toolbar spacing, sizing, and metadata behavior changed. The toolbar no longer displays the per-file diff line statistic.

Changes

Pull request layout

Layer / File(s)	Summary
Code toolbar layout apps/web/src/components/pullRequest/PullRequestCodeTab.tsx	The toolbar now wraps with updated spacing and padding. Metadata remains uncompressed. Scope controls have width constraints. The per-file diff line statistic and its supporting memo and import were removed.
Pull request tab bar layout apps/web/src/components/pullRequest/PullRequestDetailPanel.tsx	The tab bar now wraps with increased gaps instead of horizontal scrolling. The toggle group does not shrink.

Priority: ⬇️ Low

Estimated code review effort: 1 (Trivial) | ~5 minutes

Change: Bug fix

Merge Risk: 🔵 Low · up to ec66f

On narrow panels, some Code toolbar controls can be pushed outside the visible area. Restore wrapping before merge to keep those controls usable.

The docstring coverage warning concerns existing functions. This PR changes only CSS classes and adds no functions or APIs. Adding docstrings would be outside this layout fix and conflict with the requested scope, so I am leaving that non-blocking warning unchanged.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Allow the Code toolbar to wrap at narrow widths.

At a 360px panel, horizontal padding leaves 328px for the toolbar. When files exist, the right shrink-0 group renders five fixed-size controls. With a selected commit, withheld content, inline-comment metadata, and a sufficiently large file count, the non-truncated PullRequestMetaLine and the commit trigger exceed the remaining width. The non-wrapping row then places the rightmost controls outside the visible toolbar. Restore flex-wrap, basis-40, gap-x-2 gap-y-1, py-1, and min-h-10 so the controls move to a visible second row.
