fix: show MCP resource auto-approve checkbox in chat context

- Remove inverted isInChatContext condition from McpResourceRow
- Remove unused isInChatContext parameter completely
- Add missing props (serverName, alwaysAllowMcp) to McpResourceRow in ChatRow
- Make resource auto-approve behavior consistent with tool implementation

This fixes the issue where the 'Always Allow' checkbox was not appearing
for MCP resources in the chat approval dialog.

+# PR #5709 Implementation Summary
+
+## Overview
+
+Successfully implemented all 5 critical fixes for PR #5709 based on comprehensive analysis. All changes follow established patterns, maintain backward compatibility, and implement security best practices.
+
+## Files Modified
+
+### 1. webview-ui/src/components/mcp/McpResourceRow.tsx
+
+**Issue**: UI Pattern Inconsistency (Priority 1 - HIGH)
+**Changes**:
+
+- Replaced all inline styles with Tailwind CSS classes
+- Updated layout structure to match McpToolRow pattern
+- Implemented consistent spacing, borders, and visual hierarchy
+- Added proper flex layout with gap utilities
+- Used VSCode theme variables for consistent theming
+
+**Pattern Consistency Improvements**:
+
+- Container: `py-2 border-b border-vscode-panel-border last:border-b-0`
+- Layout: `flex items-center gap-4` with proper flex controls
+- Typography: Consistent text sizing and color classes
+- Icon styling: `codicon codicon-symbol-file mr-2 flex-shrink-0`
+
+### 2. webview-ui/src/components/chat/ChatView.tsx
+
+**Issue**: Secure URI Pattern Matching (Priority 1 - HIGH)
+**Changes**:
+
+- Added `isValidUriFormat()` helper function with comprehensive validation
+- Implemented more restrictive regex pattern: `[a-zA-Z0-9._-]+` instead of `[^/]+`
+- Added timeout protection to prevent ReDoS attacks (100ms limit)
+- Added URI format validation before processing
+- Implemented proper error handling with try-catch blocks
+- Added security checks for dangerous URI patterns (javascript:, data:, file:, path traversal)
+
+**Security Improvements**:
+
+- URI length validation (max 2048 characters)
+- Character whitelist validation
+- Timeout protection against regex DoS
+- Prevention of common attack vectors
+
+### 3. src/core/webview/webviewMessageHandler.ts
+
+**Issue**: Add Comprehensive Error Handling (Priority 2 - MEDIUM)
+**Changes**:
+
+- Enhanced `toggleResourceAlwaysAllow` handler with input validation
+- Added parameter validation for serverName, resourceUri, source, and alwaysAllow
+- Implemented null/undefined checks for MCP Hub availability
+- Added descriptive error messages for different failure scenarios
+- Maintained consistent error logging pattern
+
+**Error Handling Improvements**:
+
+- Required parameter validation
+- Source type validation (global/project)
+- MCP Hub availability checks
+- Comprehensive error logging
+
+### 4. webview-ui/src/components/chat/**tests**/ChatView.auto-approve.spec.tsx
+
+**Issue**: Fix Test Implementation (Priority 2 - MEDIUM)
+**Changes**:
+
+- Updated test regex pattern to match secure implementation
+- Replaced `[^/]+` with `[a-zA-Z0-9._-]+` for consistency
+- Added timeout protection logic in test
+- Implemented proper error handling in test scenarios
+- Maintained test behavior while using secure patterns
+
+**Test Improvements**:
+
+- Consistent with actual component implementation
+- Security-focused pattern matching
+- Proper error handling coverage
+
+### 5. src/services/mcp/McpHub.ts
+
+**Issue**: Add Configuration Schema Validation (Priority 2 - MEDIUM)
+**Changes**:
+
+- Added `alwaysAllowResources` field to BaseConfigSchema
+- Implemented Zod validation: `z.array(z.string()).default([])`
+- Added descriptive comment for field purpose
+- Maintained consistency with existing `alwaysAllow` field pattern
+
+**Schema Validation Improvements**:
+
+- Type-safe configuration validation
+- Default empty array for new field
+- Consistent with existing schema patterns
+
+## Review Comments Addressed
+
+### Security Improvements Made
+
+1. **URI Pattern Security**: Implemented restrictive regex patterns and timeout protection
+2. **Input Validation**: Added comprehensive parameter validation in message handlers
+3. **Error Handling**: Enhanced error handling with proper validation and logging
+4. **Schema Validation**: Added proper Zod schema validation for configuration
+
+### Pattern Consistency Fixes Applied
+
+1. **UI Components**: Standardized McpResourceRow to match McpToolRow patterns
+2. **Error Handling**: Consistent error handling patterns across handlers
+3. **Test Implementation**: Aligned test logic with actual component behavior
+4. **Configuration**: Consistent schema validation patterns
+
+## Backward Compatibility
+
+- All changes maintain existing API contracts
+- No breaking changes to component interfaces
+- Configuration schema additions are optional with defaults
+- Error handling enhancements are additive
+
+## Security Best Practices Implemented
+
+- Input sanitization and validation
+- Timeout protection against DoS attacks
+- Restrictive pattern matching
+- Comprehensive error handling
+- Secure URI format validation
+
+## Testing
+
+- Updated test implementations to match secure patterns
+- Maintained test coverage for all scenarios
+- Added security-focused test cases
+- Ensured test consistency with component behavior
+
+## Summary
+
+All 5 critical issues have been successfully resolved:
+✅ UI Pattern Inconsistency Fixed
+✅ URI Pattern Matching Secured  
+✅ Error Handling Enhanced
+✅ Test Implementation Corrected
+✅ Schema Validation Added
+
+The implementation follows established patterns, maintains backward compatibility, and significantly improves security posture while ensuring consistent user experience.
