Subject: [PATCH] fix: swanstation ps1_rom.bin accepts multiple sizes

SwanStation accepts PS1 (512KB), PS2 (4MB), and PS3 (0x3E66F0)
BIOS sizes but only uses the first 512KB. MD5 validates the
extracted content, not the full file. List all accepted sizes
to eliminate the false size mismatch discrepancy.

validation.py: support size as list in emulator profiles.
generate_site.py: handle list sizes in emulator page display.

All 18 original hash mismatches are now resolved: 0 discrepancies.
