fix: add Stream Deck XL and other missing device layouts to MODEL_LAYOUTS

The MODEL_LAYOUTS dict only contained the Original (20GBA9901) and Virtual
(UI Stream Deck) models. Any other device — including the XL — fell through
to the 5×3 fallback, making it impossible to address all 32 keys.

Added models:
- Stream Deck MK.2 (20GAA9901) — 5×3, 15 keys
- Stream Deck XL (20GAT9902) — 8×4, 32 keys
- Stream Deck XL rev2 (20GBA9902) — 8×4, 32 keys
- Stream Deck Mini (20GAI9501) — 3×2, 6 keys
- Stream Deck Neo (20GBD9901) — 4×2, 8 keys + touchscreen
