chore(lint): resolve JSDoc warnings from wp-scripts 36 - #194

Clears the 31 lint warnings that @wordpress/eslint-plugin 27 (via @wordpress/scripts 36) started reporting in src/. Only doc comments change; no code does.

• jsdoc/reject-function-type (24): each {Function} is now the callback's real signature, taken from how it is called, for example {(images: string[]) => void} or {(status: string, options?: Object) => void}.
• jsdoc/escape-inline-tags (7): package names such as @wordpress/editor in doc comments are now wrapped in backticks, so they are not read as JSDoc tags.

lint-js --fix realigned the affected @param blocks to the wider type column, which accounts for most of the diff.

Testing

• npm run lint: 0 errors, 0 warnings (was 31 warnings).
• npm run build compiles; npm run test:unit: 364 passed.
• Checked that every changed line is inside a doc comment.
