Pin live boot medium to versioned ISO label

New in chart:
- event_logs and platform_config sections in viewer
- Storage columns: logical_block_size_bytes, physical_block_size_bytes,
  metadata_bytes_per_block
- Compact status/severity icons, severity filtering for event logs
- Fixed JS MIME type and base stylesheet

bee audit schema already has all required fields; no schema changes needed.
