feat: add logs UI — tRPC router, page, and sidebar nav

- logRouter with list (infinite query, cursor-based) and severityCounts procedures
- /logs route page: severity filter chips with counts, search input, expandable log rows
- Log detail expansion shows attributes, resource, trace context, device/location
- Sidebar "Logs" link with ScrollText icon between Events and Sessions
