[PATCH v2 0/5] gitweb: fix broken mobile layouts across views

Summary =======

This patch series fixes mobile responsiveness bugs that currently break page layouts in gitweb. The approach is adaptive rather than transformative: preserve legacy desktop layout, add targeted mobile constraints at ≤768, and prevent content from escaping its containers and breaking the layout.

Changes since v1:

 * End-state behavior is unchanged; this reroll improves patch sequencing
   and message precision.
 * [2/5] now introduces the mobile @media (max-width: 768px) block and
   places the div.projsearch/input constraints there directly.
 * [3/5] now extends that existing media block with the remaining
   log/commit/blob/diff mobile overflow fixes, instead of moving search
   rules.
 * [3/5] commit message updated to match the patch flow and to clarify that
   overflow-wrap:anywhere on div.log_body is intentionally global.

Rationale =========

Software development has traditionally been desktop-first and remains the primary environment, but common contributor tasks like browsing history, reading logs, reviewing diffs, and sharing links are increasingly done on mobile devices while away from the workstation. This patch series aims to support the emerging need by improving day-to-day usability for contributors accessing gitweb on small screens.

Log ===

Before log-BEFORE [https://github.com/user-attachments/assets/6f64ffea-0975-4d67-a1b4-35b471986ab0]

After Note: certain inputs contain non-breaking/escaped spaces (e.g., NBSP), so the renderer treats the surrounding text as a single long continous string. Under constrained widths this can present as “mid-word” wrapping, but it is the correct handling of long strings; addressing that is a content-normalization concern, not a layout concern. log-AFTER [https://github.com/user-attachments/assets/f8852e95-4f31-4337-9b21-6d94232b1be7]

     -    Add a shared mobile media query to rebalance those layouts: reduce or clear
     -    paddings in log/commit sections, keep header/search content within the

     +    Extend the existing mobile media query to rebalance those layouts: reduce
     +    or clear paddings in log/commit sections, and allow horizontal scrolling
     +    for preformatted blob/diff content instead of forcing page-wide overflow.

     +    All layout adjustments in this patch are mobile-scoped, except one global
     +    safeguard: set overflow-wrap:anywhere on div.log_body. Log content can
     +    contain escaped or non-breaking text that behaves like a single long token
     +    and can overflow at any viewport width, including desktop.
