Fix API key changes not triggering container recreation

The container was only recreated when the auth mode changed, not when
the API key value itself changed. This meant saving a new key required
a manual container rebuild. Now we store a hash of the API key as a
Docker label and compare it on start, so a key change automatically
recreates the container (preserving the claude config volume).

Also adds a note to the global AWS settings UI that changes require a
container rebuild.
