maziggy 6f050708da Fix: cap TLS to v1.2 for P2S FTPS to dodge vsFTPd session-reuse bug (#1401) ...

Python 3.13 negotiates TLS 1.3 by default. The P2S firmware 01.02.00.00
  vsFTPd build doesn't tolerate TLS 1.3's async session-ticket model on
  the FTPS data channel — session resumption races, the data channel gets
  torn down mid-stream, uploads land truncated at a chunk boundary, and
  the printer replies 426 instead of 226. Visible to the user as "unable
  to parse 3mf file" 30 s into the print.

  Capping the SSL context's maximum_version to TLS 1.2 makes session
  resumption synchronous and uploads complete normally.

  Follow the per-model pattern established by camera_profiles.py in the
  #1395 follow-up: add backend/app/services/ftp_profiles.py with a frozen
  FTPProfile dataclass and a per-model registry. Only P2S (display name
  + N7 SSDP code) gets the cap today. X1C, H2D, P1S, A1 stay on negotiated
  TLS 1.3 — the maintainer's dogfooded printers see zero behaviour change.
