perf(bundle): keep Zod off the first load of four eager routes

zod 4.6 grew the shared Zod chunk from 63 to 89 KB gz (the new schema
compiler and its memoizer ride along because every schema goes through
the `z` namespace), and the dashboard, measurements, mood and settings
routes each carried it for values that need no validation.

Move the measurement source list, the notes limit, the screening check
and the Coach source list into value-only modules the schemas are built
from, import the settings classifier and response check from their
leaves, and load the gate's managed settings and anamnesis sections on
demand. Re-base the four route baselines to the measured values and the
aggregate cap to 4975, with the reason in the budget comment.
