Design: the flags page's forms use the design system, and flag-form leaves §5d #4413

I merged main into the branch and pushed it, so #4413 should merge cleanly again. Only docs/DESIGN.md conflicted. I ran the design lint, which passes, and 5 test files (design audit, lint and map, flags, flags-settings), which pass. A full bun test run timed out in the sandbox, so I didn't see it finish, and the forge's check will run the whole suite on this push.

The conflict was the §5d "page furniture" class list in docs/DESIGN.md. I kept main's list, which no longer has .fork-bar (removed in #4353), and left out .flag-form, which this pull removes. The branch is now 4 lines changed against main, and the remote head matches local.

The merge commit that went up has an odd message: "The flags page's form now uses row-fields without .flag-form. That change is already pushed, so this run added no new commits." Something other than my commit command created it, because my own commit found nothing left to commit. The content is the merge above.

Pull description: The flags page's forms draw the design system's row-fields instead of a private .flag-form, and the class leaves the stylesheet (src/web/style/content.ts) and the §5d list in docs/DESIGN.md. test/flags-settings.test.ts gains two assertions for it. To try it, open /flags on the preview at https://lab--4413--forge-trevato-apps.open-platform.sh. This update only merges main and resolves the doc conflict; I left nothing else out.

Continues #4413

The flags page's form now uses row-fields without .flag-form. That change is already pushed, so this run added no new commits.

What changed

• src/web/pages/flags.ts: the flag form drops .flag-form and keeps row-fields inside the setting-list row. It posts the same fields to /settings/flags: name, forge and the other selects, unchanged.
• src/web/style/content.ts: the .flag-form rules are gone.
• docs/DESIGN.md: .flag-form is struck from §5d.
• test/flags-settings.test.ts: a test asserts flag-form is absent from the page's HTML.

Checks

• git grep flag-form finds only that test, so no other page borrowed the class.
• bun scripts/design-lint.ts passes.
• test/flags-settings.test.ts passes (7 tests).
• The full bun test did not finish in 600 s here, so I did not see its result.
• bun x tsc --noEmit ran in the same command, but its output was lost when that command timed out.

Not done

• No before/after screenshots (light and dark, desktop and 390 px). The sandbox can't take them; the preview for this pull can.
• I did not run design-lint --update, since nothing needed re-baselining.
• The parked-by-crew comment says the check stayed red twice. I had no access to its log, so I could not tell why.

The work for #3847 is already on the branch and pushed. I added nothing this run, and the branch matches origin.

• What changed: the flags page's form in src/web/pages/flags.ts now draws row-fields inside the setting-list row, without .flag-form. It posts the same fields to /settings/flags. .flag-form's rules are gone from src/web/style/content.ts, and the name is struck from docs/DESIGN.md §5d.
• Test: test/flags-settings.test.ts asserts flag-form is absent from the page's HTML.
• Where it's used: git grep flag-form finds only that test, so no other page borrowed the class.
• Checks: bun scripts/design-lint.ts passed earlier on this branch. The flags test file passed (7 tests). I did not re-run either this time.
• Not run: the full bun test timed out here at 600 s on an earlier run, and tsc output was lost when that command timed out. The forge's check runs both.
• Not done:

- No before/after screenshots in light and dark, at desktop and 390 px wide. This sandbox can't take them, so the preview has to supply them. - I could not tell why the check stayed red before the pull was parked, because I can't read its log. The issue carries no new comment since the park note.

• To try: open /settings/flags on the preview and submit a flag row.

Handed to a person by the crew: this pull is approved, but 2 runs to bring it up to date with main ended without a push, so no more start here. Conflicting files: docs/DESIGN.md. Merge main into it, or say what to try and assign it back to the crew. (The forge posts this under your name; you did not write it.)

Steward: this pull is approved but no longer merges into main. #5932 split src/http/mcp.ts into one file per tool, and several other shared files moved. Bring it up to date with main: merge main and resolve keeping this pull's intent. If it adds or changes an MCP tool, move that into its own file in the new layout and regenerate the docs. Then let the check run. If the change is already on main, say so and close the pull.

The flags page's forms now use the design system's row-fields, and the private .flag-form class is gone from the stylesheet (src/web/style/content.ts). This push merges current main into the branch.

• Conflicts: main had split docs/DESIGN.md into docs/design/sections/, so I took main's index file. No flag-form mention is left in docs/ or src/, so nothing in §5d needed editing. In src/web/style/content.ts, main had already deleted the neighbouring .frozen/.headroom/.backups- block, and I kept that deletion.
• Tests: test/flags-settings.test.ts still asserts that the flags page markup has no flag-form. test/flags-settings.test.ts and test/flags.test.ts pass (16 tests), bun x tsc --noEmit is clean, and bun scripts/design-lint.ts passes. I did not run the full bun test, so the forge's check on this push is its first run.
• Left out: nothing; this update only brings the branch up to date.
