PrintVault: remove GCode segment cap + fix PHP upload limits
Deploy HouseHub / deploy (push) Successful in 2s
Details

Browse Source 
- PHP upload: 20M → 300M, post_max: 25M → 310M, memory: 256M → 512M
- GCode parser: no segment cap (full file), flat array format for compact JSON
  491k segments = 0.8s parse, 17MB JSON on 80MB GCode file
- Viewer JS updated for flat array stride-7 format
