This PR fixes defects found while re-running the audit's QA scenarios, and removes headings that repeated the screen title.

Defects

• Evidence panel for earlier rounds. On an earlier, folded round, the evidence panel always said the evidence could not be read. That card shows the full stored result, but the check compared it only with the summary view. A shown result now passes if it is part of the summary view, the returned result or the manifest result. A result that mixes these forms is still refused, and the content comparison is unchanged.
• Answer-check note on earlier rounds. An earlier round said its answer checks were "not read yet". The server only returns checks for the latest round, so they never arrive. The note now says they are shown only on the latest round.
• Tooltips. The Blueprint "Open dropdown" tooltip, which appeared in English in every language, is removed. Citation tooltips showed span ids; they now read "Show evidence N".
• Sidebar label. The sidebar label no longer clips in English and Japanese.
• Korean particles. Two particles that followed project names are fixed.

Repeated headings

• The home screen starts with the project list. The large slogan, description and icon above it are removed.
• Eight small headings that repeated the screen title are removed, along with the "original · version · location" fragment label.

Validation

• vitest: 1,236 tests pass. This includes the three server contract test files.
• tsc and eslint pass.
• axe reports no violations on 17 screens.
• Mutation checks: 17, all caught.
• The audit's QA scenarios were re-run on a fresh workspace and build: 44 of 45 meet their criteria. The remaining one (Q-36, wide window unchanged) cannot be re-measured because later batches changed the wide window on purpose.
• Server code is unchanged.
