fix: exclude YAML frontmatter from word count in Inspector panel

The DynamicPropertiesPanel had a local countWords that used a regex
(/^---[\s\S]*?---/) which could match dashes inside frontmatter values,
leaving part of the frontmatter in the body and inflating the count.

Replace with the canonical countWords from utils/wikilinks.ts which uses
splitFrontmatter (line-based indexOf) and correctly finds the closing
delimiter on its own line.
