fix:(lock): add portrait layout support for vertical monitors

[Mestane]

Problem

The lock screen layout was designed around landscape monitors and doesn't adapt to vertical/portrait displays. On a rotated monitor the surface is sized off screen.height, which is the long edge in portrait, so the content overflows and the side columns get squeezed against the center.

So I made the lock surface orientation-aware it now sizes against the monitor's short edge regardless of rotation, and stacks the modules vertically when the screen is in portrait.

Approach

The core fix is sizing against the monitor's short edge (min(width, height)) instead of screen.height that's the dimension the design actually scales against, and screen.height only happens to match it in landscape. Orientation is detected with a plain width < height check, avoiding the undocumented lastIpcObject.transform field.

For portrait, a separate vertical layout stacks the modules top-to-bottom: weather + resources, the clock/password block, fetch + notifications, then media. The landscape layout is untouched.

Notes

Landscape behavior is unchanged on a 1440p monitor the short edge resolves to 1440 and the scale to 1.0, identical to before, so this is a no-op for existing setups.

Tested on a dual-monitor setup with one landscape (DP-2) and one portrait display (DP-3, transform = 1).
