fix: prevent repeated redirect when switching from grid to sidebar view

The default-view redirect in HomePage fired on every mount, not just the
initial page load. A module-level flag now gates the redirect so it only
applies once per session, allowing users to switch to sidebar view when
grid is the default.

Closes #128
