Remove deprecated `login` and `logout` commands

[Copilot]

The deprecated azd login and azd logout commands, previously hidden from help and issuing deprecation warnings, are now fully removed. Users must use azd auth login and azd auth logout.

Changes

• Command registration: Removed login and logout from root command tree in root.go
• Dead code cleanup: Removed newLoginFlags() and newLoginAction() helpers that were only used by the deprecated command paths
• Test migration: Updated functional test from azd login to azd auth login
• User-friendly error messages: Added helpful error messages in auto_install.go that direct users to the correct commands when they attempt to use the removed commands

Behavior

$ azd login
Error: The 'azd login' command has been removed.
Please use 'azd auth login' instead.

$ azd logout
Error: The 'azd logout' command has been removed.
Please use 'azd auth logout' instead.

$ azd auth login --help
Log in to Azure.
[...]

The deprecation warning code in auth_login.go remains as it's still used to differentiate between azd auth login (no warning) and the now-removed azd login (showed warning) via the loginCmdParentAnnotation check.

@copilot if a user runs azd login or azd logout please return a message directing them to use the related auth login/logout commands.

Done! When users run azd login or azd logout, they now see:

Error: The 'azd login' command has been removed.
Please use 'azd auth login' instead.

Implemented in commit 8fa5931.

[!WARNING]

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

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)
