Improve issue and approvals UI: parent chain, project names, approval details

shared:
- Add IssueAncestor type and ancestors?: IssueAncestor[] to Issue interface

IssueDetail:
- Show clickable parent chain breadcrumb above issue title when issue has parents
- Ancestors rendered root-first (reversed from API order) with chevron separators

IssueProperties:
- Project field now shows project name with a link instead of raw UUID
- Assignee field now links to agent detail page
- Parent field shows immediate parent title (from ancestors[0]) with link
- Show request depth when > 0

Approvals:
- Pending/All filter tabs with pending count badge
- HireAgentPayload renders name, role, title, capabilities, adapter type
- CeoStrategyPayload renders plan/description text in a monospace block
- Decision note shown when present
- Requester agent name shown in header
- Approve button uses green styling; empty state with icon
