Add automatic company logo fetching during workspace creation (#9158)

Closes #9151 

## Description
This PR automatically sets a workspace's logo based on the user's work
email domain during signup. When a user creates a new workspace using
their work email (e.g., @airbnb.com), the system will fetch and set
their company logo from twenty-icons.com as the default workspace logo.

## Implementation Details
- Added a new `CompanyEnrichmentService` to handle company-related data
enrichment
- Created a modular architecture that supports future enrichment
features (e.g., company name, details)
- Integrated with existing work email detection
- Maintains user ability to override the logo later

## Testing

https://github.com/user-attachments/assets/f7855c99-462a-4053-9e52-29649e954275


I tested the following scenarios:
- Signing up with a work email (e.g., @company.com) → Logo is
automatically set
- Signing up with a personal email (e.g., @gmail.com) → No logo is set
- User can still upload a custom logo after automatic setting

## Technical Notes
- Uses existing `isWorkEmail` utility
- Structured for future extensibility (additional company data
enrichment)
- No breaking changes to existing functionality
