Add detail pages, property panels, and restyle list pages

New pages: AgentDetail, GoalDetail, IssueDetail, ProjectDetail, Inbox,
MyIssues. New feature components: AgentProperties, GoalProperties,
IssueProperties, ProjectProperties, GoalTree, NewIssueDialog. Add
heartbeats API client. Restyle all list pages (Agents, Issues, Goals,
Projects, Dashboard, Costs, Activity, Org) with EntityRow, FilterBar,
and improved layouts. Add routing for detail views.
