chore: prepare release 1.5.1

[withe-ci]

Automated release PR. Merging it tags v1.5.1, which fires release.yml (the multi-arch image build). Do not hand-edit CHANGELOG.md — it is generated from .changeset/.

Fixes

• The dashboard header now uses two lines. The first line holds the page links: all repositories, completed updates, log problems, and Renovate health. The second line holds the fleet's numbers: repositories, pending updates, lock-file refreshes, and the countdown to the next Renovate run. Before, all of these shared one line, so a count and a page link looked alike. The page links are now in a nav landmark named "Pages", so a screen reader can jump to them. A count of one now uses the singular, for example "1 repository" and "1 lock-file refresh". When the countdown goes blank in an open tab, the line no longer ends with a stray "·". (#133)
• A log line now shows why Renovate wrote it, on the run page and on the problems page. Renovate often writes a short message, such as pip-compile error. It puts the cause in another field, such as errorMessage or the message of a caught error. Until now both pages showed only the message. You saw the cause only in the downloaded log or in the detail panel under a row. Each row now shows the cause after the message, for example pip-compile error: Option -o not supported (yet). A problems search matches the cause too, so two causes of one warning stay two rows. One message keeps at most 5 causes per run, and Withe counts later causes on the plain message row. This way one noisy warning cannot fill a run's 200 rows and push out a later fatal line. Problem lines that Withe stored before this change keep their message only. When you click a row, the detail panel now scrolls into view. Before, it opened below the window on most screens, so the click seemed to do nothing. (#132)
