Escape block type names in all quoted CSS selectors.

BlockConfig.type permits arbitrary strings, but the block, inline-content, and style parse rules interpolate those strings without escaping. A type containing " or \ can alter or invalidate the selector. Add shared escaping and regression tests for regular and layout blocks.

The narrow edge case supports a minor correctness issue, not the original major claim that clipboard parsing can fail for the entire editor.

Review comment at @packages/core/src/schema/blocks/createSpec.ts at line 160:
Escape BlockConfig.type values before interpolating them into quoted CSS
selectors in the block, inline-content, and style parse rules in createSpec;
reuse one shared escaping approach across these selectors. Add regression tests
covering regular and layout blocks with type names containing quotes or
backslashes.
