jacobh2 e4719cb9ae Rework balances around per-parent days left and deduce the partner from FK
Manual entry now takes one parent's sjukpenningnivå, lägstanivå and
dubbeldagar left (plus optional reserved days) and derives the rest in
build_snapshot, shared with the scraper. The scraper also reads the
family panel and exposes a partner deduction; with two parents it is
saved as a 'deduced' snapshot (migration 002). Parent count is the single
source of entitlement: one member gets 480 days and 96 savable at age 4,
two get 240 and 48 each. Workspaces are capped at two parents.

Also lands the in-flight squash of migrations 002–011 into the initial
schema and the removal of planning_mode.

"""Tests for `app.services.leave_snapshot.build_snapshot`.
This is the ONE shared derivation both the FK scraper
(`app.scrapers.fk_scraper._extract_parental_leave`) and manual entry
(`app.services.fetch_data_service.ManualFetchService.save_manual_entry`) go
through — see its module docstring. `test_fk_scraper.py` proves the scraper
still gets identical results after the move; this file is the exhaustive,
direct unit-level coverage of the derivation and validation itself.
