CAMBS, RMI, CONSENSIO, and INLAND always export TIFs into the daily date
folder instead of PDFs, so engine.ps1's hardcoded "*.pdf" filter silently
found nothing to upload (no error, just "No PDFs" for every practice).
Added optional entity.json field "insurance_file_type" (defaults to "pdf"
when omitted, so existing entities are unaffected); the PT STMT split logic
already worked on filename regardless of extension, so no other changes
needed.
Windows PowerShell (5.1) reads .ps1 files without a UTF-8 BOM using the
system codepage, which mangles multi-byte UTF-8 characters like -> and --
into garbage that includes smart-quote characters PowerShell treats as
string terminators - this broke parsing on Melissa's PC (error at
engine.ps1:283, cascading missing-brace errors above it). Sticking to plain
ASCII avoids the whole encoding-dependent failure class.
