Abdul Rahman e518f03031 Fix: AI Agent tool errors and relation field handling (#15668)
### Problems Fixed

1. **Tool execution errors broke conversations**
- Failed tool executions showed "Processing..." indefinitely instead of
error messages
- Tool errors with `input: null` caused subsequent messages to fail with
`Missing required parameter: 'input[X].arguments'`

2. **Relation fields not saved in AI Agent**
- AI Agent couldn't save relation fields (e.g., `companyId`) when
creating/upserting records
   - Join column names weren't recognized during field validation

### Solutions

**Tool Error Handling:**
- Display error messages in UI with expandable error details
- Ensure tool parts always have valid `input` field (`input:
part.toolInput ?? {}`)
- Refactored `ToolStepRenderer` to accept complete `toolPart` object

**Relation Field Support:**
- Updated field validation in `create-record.service.ts` and
`upsert-record.service.ts`
- Check both `fieldIdByName` and `fieldIdByJoinColumnName` mappings

### Changes
- `packages/twenty-front/src/modules/ai/`
  - `ToolStepRenderer.tsx` - Error state handling
  - `AIChatAssistantMessageRenderer.tsx` - Pass complete toolPart
  - `mapDBPartToUIMessagePart.ts` - Prevent null tool input
- `packages/twenty-server/src/engine/core-modules/record-crud/services/`
  - `create-record.service.ts` - Add join column validation
  - `upsert-record.service.ts` - Add join column validation

Does the world need another CRM?

We built Twenty for three reasons:

CRMs are too expensive, and users are trapped. Companies use locked-in customer data to hike prices. It shouldn't be that way.

A fresh start is required to build a better experience. We can learn from past mistakes and craft a cohesive experience inspired by new UX patterns from tools like Notion, Airtable or Linear.

We believe in Open-source and community. Hundreds of developers are already building Twenty together. Once we have plugin capabilities, a whole ecosystem will grow around it.
