Add STORED generated columns derived from raw (text/numeric/bool/double + EAT
timestamptz via an IMMUTABLE tickets.eat_ts() wrapper). Computed for all existing
rows and auto-populated on every future ingest — raw stays the source of truth,
no loader change. Indexes on status/cluster/team/closed_at/is_actionable for the
SLA/team/closure queries.
