Fix Ruff formatting violations blocking CI style check

[Copilot]

The "Check style" CI workflow was failing due to Ruff formatting violations introduced by the Layer 223 MTProto schema update. The key constraint: CI pins ruff==0.12.5, which formats some constructs differently than newer versions.

Changes

• hydrogram/types/user_and_chats/chat.py — reformat long ternary in ChannelForbidden branch to multi-line with double quotes
• hydrogram/parser/utils.py — wrap lambda body in parentheses to satisfy Ruff's inline-comment formatting rule
• dev_tools/generate_docs_json.py — preserve the dict comprehension method-chain format expected by ruff 0.12.5 (differs from 0.15.x)
