Add interactive selector to azd env select when no environment specified

[Copilot]

Running azd env select without arguments required users to first run azd env list, then copy-paste the environment name. This adds an interactive picker when no argument is provided.

Changes

• Modified azd env select to accept 0 or 1 arguments (previously required exactly 1)
• Added interactive environment selection using console.Select() when no argument provided
• Shows error with usage guidance when no environments exist
• Updated command snapshots for help text and Fig autocomplete

Behavior

Before:

$ azd env select
Error: accepts 1 arg(s), received 0

After:

$ azd env select
? Select an environment:
  > dev
    staging
    prod

Explicit environment argument continues to work unchanged: azd env select dev

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)

This section details on the original issue you should resolve

<issue_title>[Feature] Add CLI selector to azd env select command</issue_title>
<issue_description>Please can the azd env select command have a CLI picker (like the environment selector)

$ azd env select                                 
Error: accepts 1 arg(s), received 0

Means you have to type azd env list then copy+paste the environment name to the argument of the azd env select command.

It would be simpler for the command to list the environments if no argument was specified and the user can select using a number or using a keyboard. </issue_description>
