luci-app-dockerman: fix whitespace rendering in container logs

[jjm2473]

Container logs contain significant whitespace, which gets collapsed by
normal HTML rendering, and that "white-space: pre-wrap;" preserves
that whitespace while still allowing long lines to wrap.

Reviewed 1 new commit. The   escaping approach flagged last round has been replaced with white-space: pre-wrap; on the logs container, which addresses the wrapping regression and the tab-collapsing gap as well — ansiToHtml() already rewrites \r\n/\r/\n to <br/> before the string reaches the DOM, so pre-wrap won't double up line breaks. Commit message matches its diff. One nit inline; CI on 329f284 is green (x86_64 build still running).

The code change makes sense, but the commit message does not explain the actual problem being fixed.

Saying that this was "recommended by AI" is not useful as commit history. Please describe what is wrong with the log rendering and why white-space: pre-wrap fixes it.

For example, the message could explain that container logs contain significant whitespace, which gets collapsed by normal HTML rendering, and that pre-wrap preserves that whitespace while still allowing long lines to wrap.

The commit should document the technical reason for the change, not where the suggestion came from.

Commit checks

• 61f8734f "luci-app-dockerman: fix whitespace rendering in container logs" — the body's second clause is a dangling fragment (..., and that "white-space: pre-wrap;" preserves ...), because the "the message could explain that" framing it was copied from was dropped. Make it two sentences, e.g. "Container logs contain significant whitespace, which gets collapsed by normal HTML rendering. white-space: pre-wrap preserves that whitespace while still allowing long lines to wrap."
