v1.2.0: Enhanced Inspur/Kaytus parser with GPU, PCIe, and storage support

Major improvements:
- Add CSV SEL event parser for Kaytus firmware format
- Add PCIe device parser with link speed/width detection
- Add GPU temperature and PCIe link monitoring
- Add disk backplane parser for storage bay information
- Fix memory module detection (only show installed DIMMs)

Parser enhancements:
- Parse RESTful PCIe Device info (max/current link width/speed)
- Parse GPU sensor data (core and memory temperatures)
- Parse diskbackplane info (slot count, installed drives)
- Parse SEL events from CSV format (selelist.csv)
- Fix memory Present status logic (check mem_mod_status)

Web interface improvements:
- Add PCIe link degradation highlighting (red when current < max)
- Add storage table with Present status and location
- Update memory specification to show only installed modules with frequency
- Sort events from newest to oldest
- Filter out N/A serial numbers from display
