McAwesome Configurator

Fixed

• Removed stale development test-provider snapshots automatically when the test fixture is inactive, preventing those synthetic providers from inflating a character's displayed addon count.
• Kept custom addon settings below the Configurator-owned title and description so addon headings and first controls no longer overlap the tab header.
• Formatted initial fractional slider values consistently instead of displaying floating-point precision noise.
• Preferred the client's full-name identity API before falling back to the shorter unit-name lookup.
