<issue_title>Add next to the clock and date the option to see my battery percentage</issue_title>
<issue_description>Hi, when I have my taskbar mostly unlocked so its hidden unless I need to check my battery status,
I would like when I open my launcher to see next to the clock on the right my battery percentage instead of opening the taskbar.

Thank you very much </issue_description>

Summary by cubic

Adds an optional battery percentage next to the clock, controlled by a new setting and powered by PowerStatus, using the ClockBox style.

Summary of changes

• Changed: Clock/date loop now reads battery status when enabled; BatteryBox uses ClockBox style in main UI and settings preview; packages.lock updates Flow.Launcher.Plugin to 5.2.0; reverted unnecessary non-functional changes.
• Added: PowerStatus 1.0.3; Settings.UseBattery (default off); BatteryText property and bindings; settings toggle and preview; "Battery" locale string.
• Removed: Separate BaseBatteryBox/BatteryBox styles from themes.
• Memory usage: Minimal; one PowerStatusProvider instance; short string; reuses existing timer.
• Security: Low risk; reads local system power info only; no network or elevated permissions; dependency version pinned.
• Tests: None.

@copilot Please remove BatteryBoxStyle and use the same style as clock panel

Done in 9ed4097. Removed all BatteryBox/BaseBatteryBox style definitions from Base.xaml and all theme files. The BatteryBox TextBlock in both MainWindow.xaml and the settings preview now use Style="{DynamicResource ClockBox}" directly.
