Add LOGPile BMC diagnostic log analyzer

Features:
- Modular parser architecture for vendor-specific formats
- Inspur/Kaytus parser supporting asset.json, devicefrusdr.log,
  component.log, idl.log, and syslog files
- PCI Vendor/Device ID lookup for hardware identification
- Web interface with tabs: Events, Sensors, Config, Serials, Firmware
- Server specification summary with component grouping
- Export to CSV, JSON, TXT formats
- BMC alarm parsing from IDL logs (memory errors, PSU events, etc.)
