Subject: [PATCH] Generate e2e/.env from up.sh and fix SAC deploy error

up.sh now writes contract IDs, provider URL, and keys to e2e/.env so
the E2E test works without knowing the provider-platform repo path.
This fixes E2E on machines using non-default repo locations (BASE_DIR).

Also fixed SAC deploy failing under set -e when the contract already
exists on a persistent Stellar network.
