🚀 Release: beta → master (#60)

* fix(deploy): harden VPS paths and remove monorepo residue

- Standardize deploy root handling to DEPLOY_ROOT=
  in deploy workflow and environment loader scripts
- Add fail-fast DEPLOY_ROOT directory guards in deploy paths
- Add mandatory deploy debug visibility (USER/HOME/PWD + ls of HOME/api)
  to SSH deployment steps in deploy.yml
- Remove hardcoded DEPLOY_ROOT=/api in sync-infra and rollback jobs
- Keep env contract gate mandatory before deploy:
  ./scripts/validate-env.sh --check-monitoring
- Normalize rollback and observability docs to use C:\Users\rajas/api and api.conf
- Remove legacy apps/api and fieldtrack.conf references from tracked
  source, docs, and rollback SQL comments
- Add optional safe legacy VPS repo cleanup in vps-setup.sh
  (AUTO_CLEAN_LEGACY_REPO=true)
- Keep docker/network naming aligned: api-blue, api-green, api_network

* feat(deploy): ensure log directory exists with fallback to home directory
