-- 054: 499-A form-fidelity columns + FCC reference tables
--
-- Migration 048 added most of Blocks 1/2/6 columns (affiliated_filer_*,
-- trade_names, officer 2+3, jurisdictions_served, first_telecom_service_*,
-- exempt_usf/trs/nanpa/lnp, is_state_local_gov, is_tax_exempt_501c,
-- regulatory_contact_*, itsp_regulatory_fee_email). Migration 038 gave us
-- ceo_name/ceo_title but no CEO address.
--
-- This migration closes the remaining gaps from the April 2026 audit of
-- the 2026 FCC Form 499-A Instructions (pdf at
-- docs/fcc-references/2026-FCC-Form-499A-Form-Instructions.pdf):
--
--  * Officer 1 business address (Lines 219-220 — required same as 2+3)
--  * entity_structure (drives officer count — sole-prop = 1, corp = 3)
--  * exempt_itsp (Line 603 — not in migration 048)
--  * nondisclosure_requested (Line 605)
--  * safe_harbor_election JSONB — per-category-per-quarter election state
--  * fcc_deminimis_factors reference table (Appendix A factor — 0.256 for 2026)
--  * fcc_safe_harbor_percentages reference table (64.9% VoIP / 37.1% cellular / 12.0% paging / 1.0% SMR for 2026)
