chore(ui): align prettier across all three UI workspaces and enforce it in the ui:lint chain

[JSONbored]

What

Permanent fix for the class of damage behind the #8182 docs mangling (repaired in #8192): prettier's coverage differed between what npm run format rewrites locally and what CI checks (nothing), so a local format pass could silently rewrite hand-authored or generated content.

How

• .prettierignore in every UI workspace covering the generated artifacts (public/openapi.json, routeTree.gen.ts, dist, ui-kit's CHANGELOG.md) and — deliberately — content/docs: prettier's mdx pass reformats the template-literal code inside <CodeBlock code={\…`}>` attributes, destroying embedded YAML indentation (exactly what broke the multi-runner compose example). Docs mdx stays formatter-free; its accuracy is guarded by the drift tests instead.
• One mechanical reformat bringing all three workspaces to prettier-clean (loopover-ui was 3 files away; miner-ui and ui-kit had never been formatted).
• format:check in each workspace, wired into the root ui:lint chain that CI's validate job and npm run test:ci already run — local and CI now enforce the identical surface.

Validation

ui:lint (with the three new format:checks), ui:typecheck, ui:test, and ui:build all green locally on the reformatted tree. No behavior changes — the non-config diff is purely mechanical formatting.
