feat: add DynamicToolsMode to AgentMcpResourceConfig

[edis-uipath]

Summary

• Adds a new DynamicToolsMode enum (none, schema, all) to control how MCP tools are discovered at runtime
• Adds a dynamicTools field to AgentMcpResourceConfig (defaults to none for backward compatibility)
• none: uses tool schemas from the agent resource as before
• schema: queries tools from the MCP server but filters to only those listed in availableTools
• all: queries all tools from the MCP server, ignoring availableTools
• Bumps version to 2.8.45
