fix(drying): P1 AMS drying is screen-only — stop offering it (#2533)

The reporter found what his P1S was doing, and it is in Bambu's P1 manual:
"P1S connected AMS drying functions may only be controlled from the P1S screen."
The firmware acks ams_filament_drying with result: success and then discards it,
which is why three commands on an idle printer left the AMS 2 Pro at dry_status 0.
No command can start a cycle on a P1, on any firmware, so don't offer one.

supports_drying() now excludes the P1 series outright, replacing the 01.08+ gate
carried since #292 — that version is when P1 firmware gained AMS 2 Pro support,
not remote drying, and it was never checked against a live P1. Both drying routes
refuse with a specific 400 instead of publishing a message the printer will drop;
queue and ambient auto-drying skip P1s via the same helper.

A new drying_screen_only flag keeps the control on the card, disabled, saying why
— a P1 owner needs to learn where to dry, not watch the button disappear. A cycle
started at the printer still shows with its countdown; only Stop goes away, since
a P1 ignores stop exactly as it ignores start.

Also corrects the wiki firmware matrix, which listed P1P/P1S as supported and
(separately) P2S/H2S/H2C as unsupported. 8 tests.
