feat: redesign /logs page with table UI and date range filter

- Replace timeline view with table layout (Time, Operator, Type, Message)
- Add date range filter using @mantine/dates DatePickerInput
- Add SegmentedControl for log type filter
- Disable App Logs and Settings menu on /dev
- Remove Activity Logs menu from /dev (moved to /logs)
- Add dateFrom/dateTo query params to /api/logs backend
- Import @mantine/dates/styles.css to fix datepicker styling
