Subject: [PATCH] Add hasPSRAM and psramSize fields to /info endpoint

- Added hasPSRAM boolean field indicating if hardware has PSRAM
- Added psramSize field with total PSRAM size in MB
- Kept existing psram field for backward compatibility (free PSRAM in bytes)
- All fields only included for ESP32 architecture
- Tests passed and firmware builds successfully
