create_month copies every budget entry into month_entry with
origin_name/origin_planned retained, resolves the budget's debt target
through source_entry_id to the corresponding MonthEntry, and is
idempotent. deviation_state classifies each row as unchanged, edited,
or new_in_month. Year-month handling (validation, shift across year
boundaries) lives here so the route layer stays thin.

A month is a snapshot of the budget. MonthEntry holds the copied planned
amount plus applied and origin_name/origin_planned so the UI can mark
edited rows. source_entry_id links back to the budget but is nullable
with ON DELETE SET NULL, so deleting a budget row after snapshot leaves
the month intact. MonthDebtTarget is one row per month via CASCADE from
month.

Sections stack vertically under a fixed-width column. Each
section renders a table with two data columns (name, amount)
plus a delete action. The Primary Debt Target now sits between
Debt Minimums and Food and Essentials and uses a dashed rule to
distinguish it from sections that accept freeform entries.

Service-level and route-level coverage. Route tests share an
in-memory SQLite engine across threads via StaticPool and
override the get_session dependency.

Index view renders one card per section plus the Primary Debt
Target card. Adding or deleting a Debt Minimums entry returns the
section partial plus an out-of-band swap for the target card so
the target dropdown stays in sync without a reload.

Entry stores one row per section entry (name, amount, timestamps).
DebtTarget is a singleton table (CHECK id = 1) with a nullable
foreign key to Entry using ON DELETE SET NULL so deleting the
referenced Debt Minimums row clears the pointer.
