Replaced button/div onClick + navigate() patterns with React Router
<Link> components so that cmd-click (or ctrl-click) opens pages in a
new browser tab. Changes across:
- AgentDetail: RunListItem, "Issues Touched" items, "Manage" config
link, "Back to runs" mobile button
- CompanySwitcher: "Company Settings" and "Manage Companies" items
- Approvals: pass detailLink prop instead of onOpen callback
- Org: OrgTree nodes now render as Links
