fix: add accessible names to interactive controls across 21 views

[laurentiu021]

Summary

Adds AutomationProperties.Name to interactive controls across 21 views that lacked
accessible names, so screen readers announce them meaningfully. Generated by a per-view
pass where each view was checked first (a prior accessibility pass — #830/833/835/837/
839/841/843 — already named many controls; those were left untouched and not duplicated).

Scope

~144 names added across: DnsHosts, DiskAnalyzer, DuplicateFile, AppBlocker,
ShortcutCleaner, ContextMenu, BulkInstaller, DeepCleanup, FileShredder, Logs, Ping,
Privacy, ProcessManager, Services, SpeedTest, ThemePopup, Traceroute, Uninstaller,
AppAlerts, AppUpdates, Performance.

Covers: destructive buttons (Delete/Shred/Clear History), icon-only and per-row actions
(named after the row item, e.g. Remove host entry {0}, Add {0} to install list),
toggles, ComboBoxes, search/filter TextBoxes, DataGrids, and theme RadioButtons.

Guarantees

• Only the AutomationProperties.Name attribute was added — no layout, style,
  binding, value, or any other attribute changed. Zero visual change. (Verified by diff:
  every removed line is the same element re-emitted with the new attribute appended.)
• Controls that already had names were skipped (not duplicated).
• Build: main + Tests + IntegrationTests all 0 warnings / 0 errors — every added
  attribute compiles, so the XAML stays well-formed.

fix: → patch release (1.20.20). Protocol C to follow.
