"""TgCockpitService coverage: the /telegram/today aggregate composes
needs-you counts, fleet snapshot, spend, and ship state from seeded rows.

Assertions are DELTAS against a pre-seed baseline, never absolute counts —
CI runs the whole test tree in one process against one database, so other
suites' committed rows are visible here and an "empty company" cannot be
assumed.
