feat(apikeys): add rotate command

[LorrisSaintGenez]

What

• Add algolia apikeys rotate: rotates the CLI-managed API key for the current application via the Public API (POST .../api-keys/:uuid/rotate), looked up by the UUID stored in state.toml. The new key is persisted for the current application.
  • Legacy apps with no stored UUID get a clear error pointing to algolia application select.
• Fix algolia application select and algolia auth login: a migrated app can have a usable key in the keychain but no api_key_uuid in state.toml (so rotate had nothing to target). Both now regenerate a fresh CLI-managed key whenever none is on record.

Test

# Rotate the current application's CLI-managed key
algolia apikeys rotate

# On a legacy/migrated app with no stored UUID → error pointing to 'application select'
algolia apikeys rotate

# 'application select' (or 'auth login') now stores a UUID; rotate then works
algolia application select
algolia apikeys rotate
