Update Longcat presets to LongCat-2.0 (#4838)

Browse Source 
* Update Longcat presets to LongCat-2.0

* fix(proxy): classify LongCat-2.0 as text-only for media sanitizer

The Longcat presets now use LongCat-2.0, but the known_text_only_model
allowlist still only matched the retired longcat-flash-chat tail. Without
this, images pasted into a text-only LongCat-2.0 session are forwarded
upstream instead of being replaced with the unsupported-image marker,
causing a hard rejection. Add longcat-2.0 (keeping the retired name for
saved configs) and a regression test.
