add interactive profile and provider management

[Eraz1997]

Summary

• Add interactive selection prompts (matching awsb use) to every command that takes an optional provider/profile name: get, remove, rename, and providers sign-in -s.
• Add profiles edit and providers edit commands to modify existing providers and profiles, with optional flags (--region, --url, --provider, --account-id, --role) to skip the prompts.
• Make add commands interactive when one or more required flags are omitted.
• Sort providers list results alphabetically (profiles were already sorted).

Why

Managing SSO providers and profiles currently forces users to remember exact names and pass them as arguments. Interactive selection makes everyday commands faster and less error-prone, while the new edit commands allow fixing a misconfigured provider or profile without deleting and re-adding it.

Testing

• cargo fmt --check
• cargo clippy -- -D warnings
• cargo test
• cargo build
• Manual verification in an isolated ~/.aws/config: add/list/edit/rename providers and profiles, confirming sorted list output and that editing a provider propagates region/URL to linked profiles.
