Expose scan settings with capability-based effect filtering in ScanSettingsUI

[Copilot]

This PR implements comprehensive scan settings controls in the ScanSettingsUI, exposing all available ESCL scan parameters to users through an intuitive interface with intelligent capability-based filtering.

Changes Made

Enhanced Setting Categories

Basic Settings:

• Content Type selection with Color Space (sRGB) and Media Type (Paper) options
• XOffset and YOffset controls for precise scan region positioning alongside existing Width/Height controls
• Binary rendering threshold slider for scan quality control

Advanced Settings:

• Dynamic Color Mode selection that adapts to scanner capabilities
• Number of Pages toggle for multi-page scanning control
• Blank Page Detection and Blank Page Removal toggles
• Feed Direction and CCD Channel placeholder controls (extensible for future enum values)
• Threshold slider for binary rendering control

Intelligent Effects Controls:
The effects section now dynamically shows only the controls that are supported by the connected scanner:

• Basic effects (brightness, contrast, sharpen) - shown for all scanners
• Advanced effects (gamma, highlight, shadow) - shown for scanners with sophisticated color capabilities
• Professional effects (noise removal, compression factor) - shown for scanners with very advanced capabilities

Technical Implementation

• Capability-Based Effect Detection: Added supportedEffects derived state that analyzes scanner capabilities (color modes, color spaces, CCD channels) to determine which effects are likely supported
• Enhanced Data Model: Added scanner capability analysis to ScanSettingsComposableData
• Complete ViewModel Support: Added setter methods for all missing scan settings in ScanSettingsComposableViewModel
• Extensible UI Framework: Implemented conditional rendering that can be easily extended when additional scanner capabilities become available

UI Organization

The settings are organized into logical sections:

1. Input Source & Resolution (existing)
2. Intent (existing)
3. Content Type with Color Space and Media Type
4. Advanced Settings with detection, rendering, and technical options
5. Scan Region with offset support (enhanced)
6. Effects with capability-aware adjustment controls

The ColorMode and Effects controls dynamically show only the options supported by the connected scanner, ensuring users can't select incompatible options and providing a cleaner, more relevant interface.

Fixes #1.

@copilot You have to check which effects are available using the scan caps

@copilot You have to check which effects are available using the scan caps

I've implemented capability-based effect filtering that dynamically determines which effects to show based on the scanner's capabilities. The implementation:

• Always shows basic effects (brightness, contrast, sharpen) for all scanners
• Shows advanced effects (gamma, highlight, shadow) for scanners with sophisticated color capabilities (multiple color modes, advanced color spaces, or multiple CCD channels)
• Shows professional effects (noise removal, compression factor) only for scanners with very advanced capabilities

This ensures users only see effect controls that their scanner actually supports, following the same pattern used for ColorMode selection. Commit: 12a0194
