Develop - circle to search improvements, flashlight live update fix, auto app lock delay, and some bug fixes

[sameerasw]

This pull request introduces several new features and improvements across the codebase, with a focus on enhancing app lock security, gesture overlay customization, and UI component flexibility. It also removes the SecurityHandler class and related logic, streamlining the security handling process. The most significant changes are grouped by theme below.

App Lock Security Enhancements:

• Added support for "auto-lock delay" in app lock: users can now specify a delay (e.g., 1, 5, 10, 20, or 30 minutes) after which an authenticated app will be re-locked if left. This is managed via the new app_lock_auto_lock_delay_index setting and logic in AppFlowHandler, which tracks last leave times and removes authentication after the delay. [1] [2] [3] [4]

Gesture Overlay Customization:

• Added new settings for customizing the Circle to Search gesture overlay: users can now adjust the overlay height (circle_to_search_gesture_height) and enable a preview mode (circle_to_search_preview_enabled). The overlay's appearance and dimensions are updated in real time based on these preferences. [1] [2] [3] [4] [5]

UI Components:

• Introduced a new composable ConfigPickerItem, providing a reusable, customizable picker UI for configuration options with integrated haptic feedback and dropdown menu support.

Flashlight Notification Handling:

• Improved flashlight notification logic: the notification is now cancelled when the flashlight is turned off, and the notification will only show if the flashlight is on and live updates are enabled. [1] [2]

Security Handling Refactor:

• Removed the SecurityHandler class and all related code from the accessibility service, simplifying the security flow and moving direct lock actions into the service itself. [1] [2] [3] [4] [5] [6] [7]

These changes collectively improve user experience, app security, and maintainability of the codebase.
