vgsp: m105 - route every const-bank page through the proven window-0 pool
Only QMD words 32 (param) and 48 (program) went to the engine-proven
window-0 pool; banks 1/3/4/7 (words 34..46) fell to the window-1 scratch
path, which the SM appears not to resolve (m94's pre-SM failure, and the
bank-4 value never reaching the kernel: m104's injected base read back as
zero through the ULDC). Route all bank pages to window-0 (5 of 8 slots
used: 32/34/40/46/48).
