OIC UI: knowledge explorer and proposal review #230

Context

People must be able to see why a claim exists and correct it. A clear claims-and-evidence view comes before any graph visualization. Uses only the API (#228).

Behavior to implement

• Browse and search claims and entities. Filter by scope, type, status, and time.
• Claim page: statement, scope, status, valid and recorded time, supporting and contradicting evidence with source links, related claims and entities, version history, why it is stale or disputed, and a link to the investigation that produced or changed it.
• Proposal review: approve, reject with a reason, edit or qualify, request more investigation, mark disputed, confirm or correct validity dates. Every action is audited.

Acceptance criteria

• From a claim, a user can reach every piece of evidence and the originating investigation in two clicks.
• Approving or rejecting a proposal shows up in claim history with who and when.
