Replace ps5debug memory-patching with an on-console mounter.elf payload driven over TCP

Now support all jailbreakable PS5s and added PS5 games saves support. Rewritten to deploy mounter.elf via elfldr and issue save mount/search/create commands, dropping the Patch flow, per-firmware offset tables, and all RPC struct marshaling. Game titles now come from app.db.
