Replace @HostListener with host object in component decorators

[bracyw]

Description

Several components use @HostListener('window:resize') instead of the host property in the component decorator. Affected: BmsDebugPage, BmsAtAGlance, BmsSegmentView, CellView, AppNavBar.

Acceptance Criteria

• All @HostListener usages replaced with host property in component decorator
• All @HostBinding usages replaced with host property bindings
• Build and lint pass

Proposed Solution

Replace @HostListener('window:resize', ['$event']) with host: { '(window:resize)': 'onResize($event)' } in each component's decorator. Remove the @HostListener import where no longer needed.
