fix(ui): add Mode=OneWay to all Run.Text bindings

[LXBStudioLLC]

Summary

Fixes the same Run.Text binding crash class as PR #20 (SizeDisplay), but across all remaining XAML files.

Root Cause

Run.Text defaults to TwoWay binding mode in WPF. When bound to a read-only property (getter only, init-only, or a computed property like List.Count), WPF throws XamlParseException at template instantiation time, crashing the entire view when data is present.

Fixes (7 bindings across 4 files)

File	Binding	Property type
BrowserSelectionView.xaml:116	StatusText	regular setter (display-only)
DashboardView.xaml:55	Email, Phone	regular setter (display-only)
DashboardView.xaml:59	Experience.Count	read-only (List.Count)
DashboardView.xaml:62	Skills.Count	read-only (List.Count)
FindJobsView.xaml:68	Company, Location	init-only
LLMSettingsView.xaml:70	StatusText	regular setter (display-only)
LLMSettingsView.xaml:73	ModelCountText	regular setter (display-only)

Every Run Text="{Binding...}" in the codebase now has Mode=OneWay.
