All MOLLIFIER_* env vars renamed to TRIGGER_MOLLIFIER_*. The mollifier
primitive is generic — buffer + drainer + trip evaluator with no
trigger-specific assumptions at the redis-worker layer — but this
PR's webapp wiring is specifically the trigger-task mollifier, with
PII-sensitive payload handling and trigger-flow semantics. If we later
mollify another surface (deploys, schedules, etc.) those will want
their own env-var namespace; pre-prefixing now avoids a breaking
rename later.
Renames are mechanical: schema keys in env.server.ts, env.* references
across the v3/mollifier* modules, and a handful of doc-comment
mentions. The bootstrap fallback that has DRAINER_ENABLED default to
the ENABLED value is updated to read TRIGGER_MOLLIFIER_ENABLED from
process.env too. Code-side naming (classes, file names, the literal
word "mollifier") stays unchanged — the rename is env-var only.
