docs(docs): show the automation editor, run and trigger screens

[yannickmonney]

Fourteen docs screenshots for the editor, run page and trigger work that landed without images. Capturing them surfaced two product wording bugs and stale capture selectors.

Docs (en/de/fr)

• editor.md: phone layout, possible paths, a node's Shape tab, code completion, Start's fields, the Source view, the Problems list.
• execution-logs.md#failures: a failed run.
• triggers.md: schedule presets, custom times, custom interval, a webhook in two projects, the event list, and a skipped start under "Diagnose a missing start".
• Captions and alt text in all three languages; the captures are shared.

Product fixes found in the shots

• The skip notice said "It came due on 11:00 AM" for a start skipped today. It now always gives a day and a time, like the trigger's last-run line. A regression test pins today's case.
• A code failure said "The code threw a Error." The en/de/fr failure catalogs now use "an error", "an EvalError", "einen Fehler" and "une erreur". A regression test covers it.

Capture and e2e

• Since feat(platform): keep, read and replay a step-by-step record of every automation run #4647 the runs table opens a run from its row, not from a link. The docs manifest and automation-canvas.spec.ts now click the row with the run's status.
• The schedule picker's presets are a radio group, and its next-runs list is named with its zone.
• The tall trigger-section shots get a window that holds the whole section; without it, everything below the fold was captured blank.
• Demo seed:
  • reads the embedding switch only after the page unmasks;
  • accepts the 201 a first save answers;
  • clicks Test run until the start request leaves;
  • asks the runs API whether a run exists, instead of waiting 20 s for a row link that never renders.

Checks run locally

• docs suite: 688 passed.
• lint:links: every link lands.
• Platform tsc: clean. oxlint --type-aware on touched files: 0 issues.
• Automations UI suite: 1,161 passed.
• i18n and guards: 797 passed.
• automation-canvas.spec.ts against a local stack: passed.
• All 14 shots were captured on a fresh stack and checked by eye.

Known gap, not in this PR: the seed's project-agents step finds no model in the New agent dialog on a fresh capture stack. The automation shots were captured around it with --skip-seed.
