fix: Make AgentDto configuration fields nullable for list endpoint compatibility

Browse Source 
The backend /api/agents list endpoint returns a lightweight DTO without
configuration fields (temperature, maxTokens, systemPrompt, enableMemory,
conversationWindowSize). This caused a TypeError when parsing the response
as these fields were required in AgentDto.

Changes:
- Made 5 configuration fields nullable in AgentDto
- Updated constructor to accept optional values
- Fixed fromJson() to safely handle null values with explicit checks
- Maintains backward compatibility with full agent detail responses

This fix resolves the "Error Loading Agents" issue and allows the agents
page to display correctly. List endpoint now parses successfully while
detail endpoints still provide full configuration.

Fixes: TypeError: null: type 'Null' is not a subtype of type 'num'
