fix(ui): theme-aware modal backdrop + full-window lock overlay

Browse Source 
Address two GUI-review points:
1. Light themes no longer get a dark modal backdrop: DrawFullWindowBlurBackdrop
   now tints toward the theme app background (WithAlpha(Background(), ...)) for
   both the opaque base and the frost, so a light theme gets a light frosted
   backdrop and a dark theme a dark one. Fixes all blur overlays, not just the
   lock screen.
2. The lock screen now blurs the WHOLE window (sidebar included), not just the
   content area: renderLockScreen opens a full-viewport borderless overlay window
   (##LockOverlay, same pattern as the modal overlays / portfolio, opened from
   within ##ContentArea) with an input blocker, instead of drawing in the content
   child. Removed the theme-independent dark scrim (contradicted point 1).

Auth logic untouched. Needs GUI re-verify of all auth paths + that the whole
screen (incl. sidebar) obscures on lock and unlock returns cleanly.
