docs: add .env.example as the deployment template

`cp .env.example .env` is now the documented starting point: the tracked
template carries every variable (grouped required / sites / bot behaviour /
network / webhook / reverse proxy) with the defaults the code would use
anyway, and the compose comment plus both READMEs point at it. The proxy note
is spelled out where it matters — teloxide panics on a blank `TELOXIDE_PROXY`,
and inside a container the proxy host must be `host.docker.internal`.

Two follow-ups the template exposed:

- `RUST_LOG=` (present but blank, which `.env` makes easy) silenced the log
  again: "unset" was handled, "empty" was not. A blank value now falls back to
  the same default. Verified: blank and unset both produce the full startup
  sequence.
- `TWITTER_AUTH_TOKEN` was in the README prose but missing from the env table
  (both languages).

Verified: `docker compose --env-file .env.example config -q` resolves, and a
script comparing the compose's `${VAR}` references against the template's keys
finds none missing.

| `PIXIV_REFRESH_TOKEN` | Pixiv refresh token; Pixiv is disabled without it (a pixiv link then gets an explicit "site not enabled" reply instead of silence) |

| `EDIT_MESSAGE_TTL_SECONDS` | Edit-before-forward record expiry in seconds, default 86400; once lapsed the prompt is rewritten in place to "expired — nothing was forwarded" (no extra message) |
