Chris Lu 1ea6b0c0d9 cleanup: deduplicate environment variable credential loading ...

Previously, `weed mini` logic duplicated the credential loading process
by creating a temporary IAM config file from environment variables.
`auth_credentials.go` also had fallback logic to load these variables.

This change:
1. Updates `auth_credentials.go` to *always* check for and merge
   AWS environment variable credentials (`AWS_ACCESS_KEY_ID`, etc.)
   into the identity list. This ensures they are available regardless
   of whether other configurations (static file or filer) are loaded.
2. Removes the redundant file creation logic from `weed/command/mini.go`.
3. Updates `weed mini` user messages to accurately reflect that
   credentials are loaded from environment variables in-memory.

This results in a cleaner implementation where `weed/s3api` manages
all credential loading logic, and `weed mini` simply relies on it.
