Simple session creation from VFolder detail modal

## Objective

To simplify session creation from the VFolder detail modal, allowing users to quickly generate sessions with minimal clicks.

## Context

Currently, users can create sessions like file browser and SFTP upload directly from the VFolder detail modal. This feature aims to generalize that process for easier access.

## Scope

- **Included**: Simplified session creation preview, direct session generation, and modification options.
- **Not Included**: Complex session configurations or unrelated features outside the VFolder detail modal.

## Success criteria

- Users can generate a session with one or two clicks.
- A simplified session creation preview is displayed.
- Users can modify session details if needed.

## Risks and dependencies

- Potential user confusion with the new simplified process.
- Dependency on the existing VFolder detail modal functionality.
