Normalize rex/siong envs to .env.example + gitignore pattern

Untracks envs/rex/.env and envs/siong/.env (kept on disk so existing
deploys keep working) and adds matching .env.example templates so a
fresh clone has something to copy from. .gitignore widens from
envs/dev/.env to envs/*/.env to cover all three deployments.

Per-deployment secrets are no longer committed; rotation deemed
unnecessary because the repo is hosted on a private self-hosted Gitea
instance.

 ## Environment configs
 
-Pre-configured `.env` files for each deployment are in the `envs/` folder:
+Per-deployment templates live in `envs/<name>/.env.example` (committed). Each operator copies the example to a sibling `.env` (gitignored — never committed) and fills in the real secrets:
+
 ```
 envs/
-├── rex/.env      # Rex deployment (port 8001)
+├── dev/.env.example      # Local development tier — see "Local Development" below
-└── siong/.env    # Siong deployment (port 8005)
+├── rex/.env.example      # Rex deployment (port 8001)
+└── siong/.env.example    # Siong deployment (port 8005)
 ```
 
-For local development, copy the desired env to the project root:
+For Portainer-hosted deployments (rex/siong):
 ```bash
-cp envs/rex/.env .env
+cp envs/rex/.env.example envs/rex/.env
-# or
+# Fill in DB_PASSWORD, CM_AGENT_*, CM_SECURITY_PIN, TELEGRAM_BOT_TOKEN, etc.
-cp envs/siong/.env .env
+# Then load the variables into the Portainer stack environment.
 ```
 
-For Portainer, load the env vars from the appropriate file into the stack environment variables.
+For local development, see the dev tier flow:
+```bash
+cp envs/dev/.env.example .env
+bash scripts/dev.sh up
+```
