mAi d3c28009de mAi: #103 - t-paliad-271 Wave 2 Tier-3 Slice A — deadline-rule primitives
Implements three Tier 3 primitives from curie's bulletproof completeness
audit (docs/research-deadlines-completeness-2026-05-25.md §10 T3.1, T3.2,
T3.5), per m's 2026-05-25 15:29 steer to build the full primitives
instead of documenting workarounds.

Primitive 1 — duration_unit='working_days':
  Calculator walks day-by-day skipping weekends + court holidays via
  HolidayService.IsNonWorkingDay. Event day is not counted; result is
  always a working day for the (country, regime). Unlocks T1.8/T1.9
  modeling and the R.198 / R.213 alt leg.

Primitive 2 — combine_op='max' (and 'min'):
  When alt_duration_value + alt_duration_unit + combine_op are set, the
  calculator evaluates both legs and picks the later (max) or earlier
  (min) of the two adjusted end dates. The DB already had two rules
  shaped this way ('31d OR 20wd, whichever is longer' — R.198 / R.213);
  the calculator was silently dropping the alt leg.

Primitive 5 — timing='before' backward snap-to-working-day:
  For backward rules (R.109.1: 1 month before oral hearing; R.109.4:
  2 weeks before) the calculator now snaps to the PRECEDING working day
  when the computed cut-off lands on a weekend/holiday. Forward snap
  (the prior behavior) would push the cut-off past the statutory limit
  and miss the deadline. Adds HolidayService.AdjustForNonWorkingDays-
  Backward as the symmetric counterpart of AdjustForNonWorkingDays.

Migration 128 — DB schema:
  Adds CHECK constraints on deadline_rules.duration_unit and
  alt_duration_unit pinning the allowed set to days/weeks/months/
  working_days. Live data audited and passes (no rows excluded).

Tests (12 new + 1 flipped):
  - 5 working_days cases: forward over weekend, 20wd anchored on Fri,
    across Karfreitag/Ostermontag, across year boundary, backward
    from Friday, anchored on Saturday.
  - 2 backward snap cases: Sun → preceding Fri; cluster Sun → Sat →
    Karfreitag → Thu.
  - 4 combine_op cases: max with primary winning, max with alt winning
    over Christmas+Neujahr cluster, min with primary winning, NULL-alt
    short-circuit.
  - TestCalculateEndDate_BeforeTiming renamed and flipped from forward
    (Sun → Mon, the prior wrong behavior) to backward (Sun → Fri).

No regression on existing rules: every pre-existing days/weeks/months
'after' rule still computes the same date. Frontend build + full
go test ./internal/... clean.

Slot 128 assigned per next-available convention (mig 127 = Wave 0
Tier-0 fixes, mig 128 = Wave 2 Tier-3 Slice A primitives).

-- Revert t-paliad-271 Wave 2 Tier-3 Slice A — drop duration_unit /
-- alt_duration_unit CHECK constraints. Pre-mig-128 the columns accepted
-- arbitrary text, so dropping the CHECKs restores that shape exactly.
-- No data revert necessary — the constraint addition was purely
-- additive and validated against live data before adding.
