Local-Only Sync Option for TypingMind Teams

Goal: Implement an optional setting for users in TypingMind Teams to disable Cloud Sync and store chat history exclusively on their local device.

Justification:

1. Data Sovereignty: This option is essential for organizations with strict data control policies that mandate that sensitive conversational data must not be stored on third-party cloud services.

2. User Flexibility: It provides users with full control over their data, allowing them to remain logged in and retain chat history locally (preventing data loss) without utilizing cloud storage.

3. Market Competitiveness: Addressing the "Where is my data?" question with a definitive "Local Only" option will be a major differentiator, especially for enterprise clients concerned with security and compliance.

Proposed Implementation:

- User Setting: A toggle within the user’s settings panel labeled "Cloud Sync: On/Off" or "Storage Preference: Cloud / Local Only."

- Admin Control (woult be nice): An optional admin-level setting to enforce "Local Only" mode for specific users or the entire team.
