feat: clearer, disambiguated tool names across all surfaces (#520)

Renames 18 ambiguous or hard-to-search tool names so image tools self-qualify like the other modalities ("Compress" becomes "Compress Image"), and cleans up a few awkward names. Propagated across search (constants.ts), display (en.ts + 20 locales), the OpenAPI base spec + 20 locale specs, and the docs tool-page headings in 21 languages. Removes the duplicate "Normalize Audio" summary shared by the video and audio endpoints. Tool ids and routes are unchanged, so no API paths or bookmarks break.
