[GUI] Build OL and Buffer control panels

[Weidows]

Description

Build the OL (Opacity Listener) and Buffer control panels.

OL Control Panel

• Service on/off toggle
• Table of window matching rules:
  • Title regex (editable)
  • Opacity slider (0-255)
  • Add/remove rows
• "List Windows" button — shows all visible windows with handle and title
• Pre-fill test: select a window from the list to auto-generate a regex pattern
• Scan interval input (seconds)

Buffer Control Panel

• Mount/Unmount buttons with status indicator
• Source path selector (file dialog)
• Drive letter selector (dropdown: X:, Y:, Z:)
• Strategy selector: monitoring / defrag / download / migration / balanced
• Memory limit slider (32MB - 512MB)
• Flush interval input (seconds)
• Enable read cache / write buffer toggles
• Current status display (mounted path, strategy, cache hits/misses)

Acceptance Criteria

• OL can be started/stopped, rules editable
• "List Windows" shows actual windows from win32.EnumWindows
• Buffer can mount/unmount with configurable parameters
• Buffer status shows real-time metrics
