[FEAT] Implement members invites

[martian56]

This pull request introduces a comprehensive workspace invitation system, allowing workspace owners to invite users by email and manage invitations. It includes database schema changes, new API endpoints, and OAuth improvements to support invitation tokens during authentication flows.

Key changes:

Workspace Invitation Feature

• Added a new WorkspaceInvitation model, including fields for email, role, token, inviter, expiration, and acceptance tracking, with relationships to Workspace and User. (api/app/app/modules/workspaces/model.py)
• Created Alembic migration to add the workspace_invitations table, with appropriate indexes and foreign keys. (api/app/alembic/versions/7d6ba2fe0af9_feat_add_workspace_invitations_table.py)
• Updated Alembic env imports to include WorkspaceInvitation for metadata. (api/app/alembic/env.py)

API Endpoints for Invitations

• Implemented endpoints to create, list, retrieve, and accept workspace invitations, including permission checks to restrict actions to workspace owners. (api/app/app/modules/workspaces/invitations.py, api/app/app/modules/workspaces/router.py) [1] [2]
• Added Pydantic schemas for invitation creation, response, acceptance, and listing. (api/app/app/modules/workspaces/schemas.py)

Repository and Service Layer Support

• Added repository functions for creating, retrieving, listing, and accepting invitations, including expiration and acceptance logic. (api/app/app/modules/workspaces/repository.py)
• Implemented service layer logic to enforce owner-only actions and handle invitation acceptance, including auto-adding users to the workspace upon acceptance. (api/app/app/modules/workspaces/service.py)

OAuth Flow Enhancements

• Modified OAuth state handling to support an optional invite_token, storing it in Redis and appending it to the frontend callback URL if present. (api/app/app/core/redis.py, api/app/app/modules/auth/router.py) [1] [2] [3] [4] [5] [6]

Miscellaneous

• Bumped the API version to 0.1.0 in pyproject.toml to reflect these new features. (api/app/pyproject.toml)

Closes #11
