The Log tab provided a service health panel and log viewer. These are
consolidated into the Server tab with a new ServerHealthSection component
that encapsulates all log-related functionality.
- Extract service health panel and log viewer into ServerHealthSection component
- Add severity-based log line color coding (ERROR=red, WARNING=yellow, DEBUG=gray)
- Implement log filtering, line count selection, and auto-refresh controls
- Scroll to bottom when new log data arrives
- Render health metrics grid with version, jail count, bans, failures
- Show read-only log level and log target in health section
- Handle non-file targets with informational banner
- Import ServerHealthSection in ServerTab and render after map thresholds
- Remove LogTab component import from ConfigPage
- Remove 'log' from TabValue type
- Remove Log tab element from TabList
- Remove conditional render for LogTab
- Remove LogTab from barrel export (index.ts)
- Delete LogTab.tsx and LogTab.test.tsx files
- Update ConfigPage docstring
All 115 frontend tests pass (8 fewer due to deleted LogTab tests).
