feat(ai): add view management tools for AI chat (#16495)

## Summary

Adds a new **VIEW** tool category for the AI chat, enabling it to work
with views:

- **get-views**: List views in the workspace, optionally filtered by
object metadata ID
- **get-view-query-parameters**: Convert a view's filters and sorts into
GraphQL query parameters that can be passed to existing `find_*` data
tools
- **create-view**, **update-view**, **delete-view**: CRUD operations for
view management

### Key design decisions

1. **No pagination duplication**: Instead of creating a
`find-records-from-view` tool that would duplicate pagination logic,
`get-view-query-parameters` returns filter/sort parameters that the AI
can pass to existing record-fetching tools.

2. **Permission model**:
- Read tools (get-views, get-view-query-parameters) are available to all
users
   - Write tools require the `VIEW` permission
   - UNLISTED views can only be modified by their creator

3. **Leverages existing utilities**: Uses
`computeRecordGqlOperationFilter` from `twenty-shared` for filter
conversion.

### Files changed

- Added `ViewToolProvider`, `ViewToolsFactory`, and
`ViewQueryParamsService`
- Added `VIEW` to `ToolCategory` enum and tool registry
- Updated `chat-execution.service.ts` to include view tools in the
catalog and pass viewId in browsing context
- Extracted shared `formatValidationErrors` utility to reduce
duplication

## Test plan

- [x] Unit tests for `ViewToolsFactory` 
- [x] Unit tests for `ViewQueryParamsService`
- [x] Lint and typecheck pass
