coverage_vault: 8 MB dev-RAM aware bounds

Browse Source 
Titles running the 8MB enhancement stream code into the extended banks
(0x200000..0x7FFFFF). The vault's 2 MB mask corrupted those capture
addresses and its bound rejected legitimate regions ("capture exceeds
PSX RAM"), which blocked compacting WipEout 3's merged capture history.
