* fix(bokslut): honest periodisering for enskild firma (K1) Stop mis-selling automatic periodisering to sole traders and give the auto-detect a materiality floor: - Remove the inert PeriodiseringAutoDetectToggle (write-only localStorage, no reader anywhere); the settings row is now a plain link to the periodisering wizard, with new i18n keys in sv+en. - Auto-detect tags suggestions under 5 000 kr as low confidence with the reason 'Under 5 000 kr: behöver normalt inte periodiseras', citing K1 (BFNAR 2006:1) for enskild firma and K2 for aktiebolag; the wizard only pre-ticks high-confidence rows, so under-floor posts land unticked. Personnel-cost lines (7xxx) are exempt: they must always be accrued. - The accruals GET route resolves companies.entity_type and threads it to the detector. - Per-line accrual hint in the invoice editors is entity-aware: new accruals.k1_hint (K1, förenklat årsbokslut) for EF, k2_hint stays for AB. - Periodisering wizard and year-end AccrualsStep relabel Revisionsarvode to Bokslutsarvode for EF, default the liability account to 2991 instead of 2992, and show a muted K1-floor intro line. All copy stays advisory (behöver normalt inte, never får inte): entity_type is a proxy since no förenklat-vs-full-årsbokslut flag exists. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(bokslut): SEK-correct materiality floor, entity-type via settings, narrower personnel exemption Review fixes on the K1 periodisering branch: - The 5 000 kr floor now compares a SEK amount: queries select currency and subtotal_sek, the floor uses the periodisation share of subtotal_sek for foreign-currency invoices, and is skipped entirely when no SEK amount is resolvable (accrual-k2-hint precedent, DECISIONS.md 2026-07-26). - The accruals route resolves entity type via getCompanyEntityType (company_settings-primary, companies fallback) instead of reading companies.entity_type directly. - The personnel-cost exemption from the floor is narrowed from startsWith('7') to /^7[0-6]/: 78xx/79xx are not personnel costs.
