feat: add Patentprozesskostenrechner fee calculation engine + API
Pure Go implementation of patent litigation cost calculator with: - Step-based GKG/RVG fee accumulator across 4 historical schedules (2005/2013/2021/2025 + Aktuell alias) - Instance multiplier tables for 8 court types (LG, OLG, BGH NZB/Rev, BPatG, BGH Null, DPMA, BPatG Canc) - Full attorney fee calculation (VG, TG, Erhöhungsgebühr Nr. 1008 VV RVG, Auslagenpauschale) - Prozesskostensicherheit computation - UPC fee data (pre-2026 and 2026 schedules with value-based brackets, recoverable costs ceilings) - Public API: POST /api/fees/calculate, GET /api/fees/schedules (no auth required) - 22 unit tests covering all calculation paths Fixes 3 Excel bugs: - Bug 1: Prozesskostensicherheit VAT formula (subtract → add) - Bug 2: Security for costs uses GKG base for court fee, not RVG - Bug 3: Expert fees included in BPatG instance total
