Add three-choice option for dev-server installation (global/local/no)

[Copilot]

Overview

Expands the dev-server installation question from a simple yes/no choice to three distinct options, allowing users to choose between global installation, local installation, or no dev-server at all.

Changes

Question Enhancement

The "Do you want to use dev-server" question now offers three choices:

1. "yes, as global installation (might need root permissions to install on Linux/macOS)" - Installs @iobroker/dev-server globally and runs the setup command
2. "yes, as a adapter own local installation (no root permissions needed)" - Adds dev-server as a local devDependency (marked as recommended)
3. "no" - Skip dev-server setup

Local Installation Support

When users select the local installation option:

• @iobroker/dev-server is automatically added to devDependencies in package.json
• A convenient npm script "dev-server": "dev-server" is added for easy execution
• No global installation is performed, avoiding potential permission issues on Linux/macOS

Global Installation (Existing Behavior)

When users select the global installation option:

• Maintains the existing behavior
• Installs @iobroker/dev-server globally
• Automatically runs the setup command with the configured admin port

Backward Compatibility

• Migration function defaults to "global" for existing projects being updated
• The initial/default value is set to "local" (recommended) for new projects
• All existing functionality is preserved

Benefits

• No root permissions needed: Local installation removes the need for sudo/administrator privileges
• Project isolation: Each adapter can have its own dev-server version
• Clearer options: Users understand the implications of each choice upfront
• Better UX: The recommended option is clearly marked

Testing

• Added baseline test for local dev-server installation
• Updated existing test to explicitly test global installation
• All 63 unit tests passing
• All 51 baseline tests passing

Closes #xyz (replace with actual issue number)

This section details on the original issue you should resolve

<issue_title>Allow to choose for dev-server if local or global dep</issue_title> <issue_description>The current "Do you want to use dev-server" question should get three options:

• as local devDep ... and add it to the package.json and add all relevant "Ignore files and such"
• as global Depenednency (with warning that it might require additional acces to be installed (and catch error if an error happens on global install)
• No

maybe also bring this question more to the from to the other tools becazse eslint, prettier and devcontainer are asked at the very beginning ... I also wondered if dev-server would come at all</issue_description>

<agent_instructions>Adjust the current "yes/no" question about dev-server into a three-choise option like

• yes, as global installation (might need root permissions to install on Linux/macOS)
• yes, as a adapter own local installation (no root permissions needed)
• no

The logic for a global installation already exists.

If a local installation is choosen add the @iobroekr/dev-server dependency to the devDependencies. No extra installation is needed klike executed for global. Add a npm js script "dev-server" which points to "dev-server"</agent_instructions>
