fix(deploy): extract TELEGRAM vars from .env without sourcing it

Browse source 
`. ./.env` choked on shell-hostile values (SMTP_PASS special chars), aborting
before TELEGRAM vars loaded and rendering an empty alertmanager.yml. Extract just
the two keys with sed instead, and warn if either is empty.

# / ${TELEGRAM_CHAT_ID}) crash-loops it ("cannot unmarshal !!str `${TELEG...`").
# We substitute the real values here from .env at deploy time. Only those two
# vars are expanded so Alertmanager's own {{ }} Go-template message is untouched.
# NB: we extract just these two keys (not `source .env`) because .env holds values
# with shell-hostile chars (e.g. SMTP_PASS) that break `. ./.env`.
