Remove batch of dead code

[lkostrowski]

Summary

This PR removes a significant batch of unused code across multiple modules, improving codebase maintainability and reducing bundle size. The changes primarily remove:

• Deprecated webhook components from custom-apps/ that have been superseded by implementations in extensions/
• Unused plugin UI components including authorization, settings, and channel configuration
• Legacy sale discount components that are no longer in use
• Dead code across various modules including fixtures, utilities, type definitions, and URL helpers

Key Changes

Webhook Management (src/custom-apps/components/)

• Removed deprecated WebhookDetailsPage, WebhookEvents, WebhookHeaders, WebhookInfo, WebhookStatus, and WebhookSubscriptionQuery components
• Updated remaining components to import from @dashboard/extensions/ instead
• Cleaned up related handlers, utilities, and test files

Plugin System (src/plugins/)

• Removed unused plugin UI components: PluginAuthorization, PluginDetailsChannelsCard, PluginInfo, PluginSecretFieldDialog, PluginSettings, PluginsDetailsPage
• Removed PluginDetails.test.ts and PluginsDetails.tsx view
• Cleaned up plugin fixtures, utilities, and URL helpers

Discounts (src/discounts/)

• Removed deprecated Sale components: SaleDetailsPage, SaleInfo, SaleListPage, SaleType, SaleValue
• Removed sale-related handlers and sort utilities
• Updated channel utilities to remove sale-specific functions

Other Modules

• Removed ControlledSwitch component from src/components/
• Cleaned up unused fixtures in apps, channels, and modeling modules
• Removed unused type exports and URL helpers across multiple files
• Simplified filter utilities in giftCards and modeling modules

Impact

• 4,512 lines removed across 79 files
• Improved code maintainability by removing unused components
• Reduced potential confusion from duplicate/deprecated implementations
• No functional changes to existing features

Testing

• Verified that removed code has no active references in the codebase
• Confirmed that remaining webhook functionality uses the correct implementations from extensions/
• All existing functionality continues to work as expected
