Hide "Leave Team" Button for Default Teams & Allow "Team" Terminology Customization

[Hitesh-Sisara]

Our application is structured similarly to Jira, where users must belong to an organization(team):

• All users must be part of a team to use the application
• Subscriptions and permissions are managed at the team level
• we have turned on Automatic Team Creation feature

Issue

When users leave their automatically created team (Default team):

• They lose access to their subscription and core functionality
• This breaks the app's fundamental team-based structure

Also, some organizations prefer terms like "Organization" or "Project" instead of "Team".

Proposed Solution

• Add option to hide "Leave Team" button for automatically created teams
• Add setting to customize terminology (Team → Organization/Project)

These changes will prevent accidental loss of access while providing better terminology flexibility.
