The reminder worker failed to start in the production bundle with
`ReferenceError: Cannot access 'l' before initialization`, taking every
nightly pg-boss job down with it (score jobs + dense-intraday retention).
Root cause is a value-level import cycle between `consolidation-base.ts`
and `drain-per-sample-cumulative.ts`: each imported values from the other.
The bundler merges the tightly-cyclic pair into one module body and hoists
`DRAIN_CUMULATIVE_CUTOFF_HOURS = CONSOLIDATION_GRACE_CUTOFF_HOURS` ahead of
the constant it reads, so the eager read hits a temporal dead zone. It only
surfaced in the production build because dev/test run the modules unbundled.
Hoist the shared leaf — `CONSOLIDATION_GRACE_CUTOFF_HOURS`, the `PerSampleRow`
shape, and the timezone day-math helpers — into a new dependency-free module
`consolidation-tz.ts`. Both sides now import from the leaf, removing the cycle
at its root. Re-export the moved names from their former homes so every
existing import site resolves unchanged.
