maziggy 0279961889 FTP auto-detection: try prot_p first, fall back to prot_c for A1 ...

User feedback indicated A1 Mini with current firmware works with prot_p
(protected/SSL data channel), not prot_c as previously assumed. Different
A1 firmware versions have different FTP SSL behavior.

Changes:
- Remove hardcoded assumption that A1 models need prot_c
- Try prot_p first for all models (including A1/A1 Mini)
- If upload/download fails on A1 models, automatically retry with prot_c
- Cache working mode per printer IP for subsequent operations
- Add force_prot_c parameter for explicit mode control

This makes FTP work across A1 firmware versions:
- New firmware: prot_p succeeds, cached
- Old firmware: prot_p fails → prot_c fallback succeeds, cached
