fix: replace 'source .env' with safe env loader in all scripts

The raw 'source .env' pattern breaks when values contain special bash
characters like ) in passwords or database URLs. This caused deploy:remote
to fail with 'syntax error near unexpected token )'.

Changes:
- Created shared/scripts/lib/load-env.sh: reads .env line-by-line with
  export instead of source, safely handling special characters
- Updated db-backup.sh, db-restore.sh, deploy-remote.sh, remote.sh to
  use the shared loader
- Reordered deploy-remote.sh: git pull now runs first (step 1) so the
  remote always has the latest scripts before running backup (step 2)
