Add external plugin review board canvas for maintainers (#4174)

* feat: add external plugin review board canvas extension

Project-scoped Copilot canvas for maintainers to triage external plugin
submissions: kanban buckets, AI review, guided re-review via sub-session,
refresh, issue/comments view, and quick /approve or /reject.

* fix: harden review board per PR feedback

- Deny framing and hide stack traces from API error responses
- Track review queue ids, restore queue state on send failure, skip queued items
- Require reject reasons; treat posted decisions as pending until the workflow closes the issue
- Invalidate browser issue cache on refresh
- Clarify paid-services guidance

* fix: keep review decisions UI-only and record external outcomes

- Remove the agent-facing post_decision action to block prompt-injected approvals/rejections
- Record opposite terminal labels as external GitHub decisions instead of reusing the pending command
- State visibly that a reject reason is required
